volunteer	for now we don't have to worry about specific points	18,883	28	[]
student	is there a rule for it	18,883	29	[]
volunteer	yeah but lets get the basics of what a stretch and shrink do	18,883	30	[]
student	okaay	18,883	31	[]
volunteer	alright so a stretch makes it towards the y axis	18,883	32	[]
volunteer	oops	18,883	33	[]
volunteer	mean closer to the x axis	18,883	34	[]
volunteer	if that makes any sense e	18,883	35	[]
volunteer	it gets like pulled towards the x axis	18,883	36	[]
volunteer	do you kinda see how	18,883	37	[]
student	oh cuz its horizontal	18,883	38	[]
student	howd you know which way it was gonna go	18,883	39	[]
volunteer	yeah	18,883	40	[]
volunteer	well think of it like a string	18,883	41	[]
volunteer	you know when its all like messy	18,883	42	[]
volunteer	it looks like this	18,883	43	[]
volunteer	but when you stretch it out	18,883	44	[]
volunteer	it becomes straight like the x axis	18,883	45	[]
volunteer	does that kind of make sense	18,883	46	[]
student	what about the way it tips?	18,883	47	[]
volunteer	sorry what do you mean by tips like how do i know it doesn't become like this	18,883	48	[]
student	you moved the top right down why didnt you move bottom left up closer to x axis instead	18,883	49	[]
volunteer	i moved both closer to the x axis	18,883	50	[]
student	oh okay	18,883	51	[]
student	would vertical lead it away then	18,883	52	[]
volunteer	yes in a way	18,883	53	[]
student	how	18,883	54	[]
volunteer	here let me show an example	18,883	55	[]
volunteer	scroll down a bit Ill draw it tghere	18,883	56	[]
volunteer	do you see the orginal line(blue)	18,883	57	[]
volunteer	crossing through at (0,-2)	18,883	58	[]
volunteer	you here?	18,883	59	[]
student	sorry checking something	18,883	60	[]
student	i see it	18,883	61	[]
volunteer	oh that's alright	18,883	62	[]
volunteer	so a horizantal stretch would be like this in red	18,883	63	[]
volunteer	it becomes more like a horizantal line	18,883	64	[]
volunteer	so now you asked	18,883	65	[]
volunteer	or vertical right	18,883	66	[]
volunteer	a vertical stretch would be a bit more different	18,883	67	[]
volunteer	you are right in thinking it would go away from the y-axis	18,883	68	[]
volunteer	i mean x axis	18,883	69	[]
volunteer	but theres one more difference	18,883	70	[]
volunteer	whereas the cross through point for a horizontal shift won't change where it crosses through	18,883	71	[]
volunteer	a vertical stretch would	18,883	72	[]
volunteer	in green is what it would look like	18,883	73	[]
student	oh okay so it leans towards y axis	18,883	74	[]
volunteer	i know i just wrote ea lot	18,883	75	[]
volunteer	yeah	18,883	76	[]
volunteer	your getting the picture	18,883	77	[]
student	is there a fotmula	18,883	78	[]
volunteer	yes	18,883	79	[]
volunteer	let me write it for you	18,883	80	[]
volunteer	g(x)=f(bx)	18,883	81	[]
student	huh	18,883	82	[]
volunteer	b = the factor	18,883	83	[]
volunteer	yeah its a bit weird	18,883	84	[]
student	ohh	18,883	85	[]
volunteer	wait	18,883	86	[]
volunteer	wait	18,883	87	[]
volunteer	wait	18,883	88	[]
volunteer	before you do anything that's the formula for the horizantal shifts	18,883	89	[]
student	x is just the x right no y includedz/	18,883	90	[]
student	?	18,883	91	[]
volunteer	g(x)=b⋅f(x)	18,883	92	[]
volunteer	yeah x is just the x	18,883	93	[]
volunteer	do you understand what f(x) means?	18,883	94	[]
student	and this is vertical stretch?	18,883	95	[]
volunteer	yeah for vertical stretch or strink	18,883	96	[]
student	f(x) is the function right	18,883	97	[]
volunteer	yeah	18,883	98	[]
volunteer	lets erase this board I'll teach you how to use this formula to solve	18,883	99	[]
volunteer	and repaste	18,883	100	[]
volunteer	the problem	18,883	101	[]
student	alrighty all these variables are confusing Mr. Smith	18,883	102	[ { "pii_type": "PERSON", "surrogate": "Mr. Smith", "start": 43, "end": 52 } ]
volunteer	yeah thats fine I'll teach you to use it	18,883	103	[]
volunteer	sorry can you repast the problem	18,883	104	[]
volunteer	it gets delted when I erase the board	18,883	105	[]
volunteer	alrighty lets first test the horizantal formula	18,883	106	[]
volunteer	do you see how in the orginal f(x) = 2x-4	18,883	107	[]
student	yes	18,883	108	[]
volunteer	can you tell me the equation	18,883	109	[]
volunteer	of the line	18,883	110	[]
volunteer	thats been transformed	18,883	111	[]
student	2x-4	18,883	112	[]
student	oh sit	18,883	113	[]
volunteer	u good	18,883	114	[]
volunteer	if you can tell me that it gets a lot easier	18,883	115	[]
student	i meant to say wait not that whoops	18,883	116	[]
volunteer	i don't really care if you curse	18,883	117	[]
volunteer	can you tell me the equation	18,883	118	[]
student	uhhh	18,883	119	[]
volunteer	i can help if you want	18,883	120	[]
student	yes pls	18,883	121	[]
volunteer	alright	18,883	122	[]
volunteer	so to find an equaiton for a line	18,883	123	[]
volunteer	we need the slope and the y intercept	18,883	124	[]
volunteer	so what's the y intercept	18,883	125	[]
volunteer	that's where	18,883	126	[]
volunteer	the line crosses the y axis	18,883	127	[]
