volunteer	I just drew a purple dot at approximately (1, -3 1/7)	14,365	254	[]
student	but isnt -2 the y intercept	14,365	255	[]
volunteer	yes	14,365	256	[]
volunteer	is my dot on the y-axis?	14,365	257	[]
student	kinda of yes	14,365	258	[]
volunteer	no	14,365	259	[]
volunteer	my dot is at x=1	14,365	260	[]
student	oh	14,365	261	[]
volunteer	and I drew a closed circle because x<=1	14,365	262	[]
student	yea	14,365	263	[]
volunteer	and I just added a small dot on the y-intercept	14,365	264	[]
student	yea i see	14,365	265	[]
volunteer	y=-8/7 x -2 is a line that goes through those points	14,365	266	[]
volunteer	but we only draw it to the left of the big dot because that equation only applies to x<=1	14,365	267	[]
student	oh becasue the x is from including 1 and up	14,365	268	[]
volunteer	1 and down	14,365	269	[]
student	oh becasue its -8/7	14,365	270	[]
volunteer	I just graphed half of the function	14,365	271	[]
volunteer	the other half is for x>1	14,365	272	[]
volunteer	that will start with an open circle because of > instead of >=	14,365	273	[]
student	yea	14,365	274	[]
volunteer	and the open circle will be at some point where x=1	14,365	275	[]
volunteer	f(x) for x>1 is 3/7 x + 15/7	14,365	276	[]
student	at 3/7?	14,365	277	[]
volunteer	we need to find that at x=1	14,365	278	[]
volunteer	x=1 is the endpoint again, but open circle instead of closed	14,365	279	[]
volunteer	how much is 3/7 times 1 plus 15/7 ?	14,365	280	[]
student	12/7	14,365	281	[]
student	-12/7	14,365	282	[]
volunteer	both are wrong	14,365	283	[]
volunteer	3/7+15/7	14,365	284	[]
student	18/7	14,365	285	[]
volunteer	which is 2 4/7, which is about 2.5	14,365	286	[]
volunteer	I drew and open circle at around (1, 2 4/7)	14,365	287	[]
student	yea i see it	14,365	288	[]
volunteer	what is the y-intercept for this equation	14,365	289	[]
volunteer	?	14,365	290	[]
student	15/7	14,365	291	[]
volunteer	yes, which is just barely above 2	14,365	292	[]
volunteer	but this one is only for x>1	14,365	293	[]
student	huh	14,365	294	[]
student	we need to find it for eerything else too?	14,365	295	[]
volunteer	you left out the x>1 part, remember?	14,365	296	[]
volunteer	first we found it for x<=1, then we found it for x>1	14,365	297	[]
volunteer	that covers everything	14,365	298	[]
student	so now we have to find x>1	14,365	299	[]
volunteer	green line going to the right from the open circle at x=1	14,365	300	[]
student	ok	14,365	301	[]
volunteer	we are done graphing	14,365	302	[]
student	ok	14,365	303	[]
student	now we can find domain and range	14,365	304	[]
volunteer	domain	14,365	305	[]
volunteer	have we covered all possible real number values of x?	14,365	306	[]
volunteer	from -infinity to infinity?	14,365	307	[]
student	the domain is from (-oo, 1] U (1, oo)	14,365	308	[]
volunteer	No	14,365	309	[]
volunteer	you don't need to break it up	14,365	310	[]
volunteer	x can be 1	14,365	311	[]
volunteer	there is no gap there	14,365	312	[]
student	when do i do break it up?	14,365	313	[]
volunteer	when there is a gap	14,365	314	[]
volunteer	like x<=1 and x>2	14,365	315	[]
volunteer	then there is a gap between 1 and 2	14,365	316	[]
student	ohhh so because both is on x=1 theres no need to break it up	14,365	317	[]
volunteer	right	14,365	318	[]
volunteer	range	14,365	319	[]
volunteer	what's the smallest value of y you see?	14,365	320	[]
student	-3 1/7	14,365	321	[]
volunteer	yes	14,365	322	[]
volunteer	just looking at the left pointing line, can y have all possible values >=-3 1/7 ?	14,365	323	[]
student	yes	14,365	324	[]
volunteer	range is [-3 1/7, infinity]	14,365	325	[]
volunteer	oope	14,365	326	[]
volunteer	StudentA	14,365	327	[ { "pii_type": "PERSON", "surrogate": "StudentA", "start": 0, "end": 8 } ]
volunteer	oops	14,365	328	[]
volunteer	infinity)	14,365	329	[]
volunteer	done	14,365	330	[]
volunteer	do you understand it, now?	14,365	331	[]
student	yes i do	14,365	332	[]
volunteer	great!	14,365	333	[]
volunteer	I've got to go, now.	14,365	334	[]
student	ok bye	14,365	335	[]
volunteer	bye	14,365	336	[]
student	bye	14,365	337	[]
volunteer	Hello, how can I help you	14,381	0	[]
student	I need help solving a math question	14,381	1	[]
volunteer	Whats the problem	14,381	2	[]
student	A scale on a hiking map shows that 3 inches represents 1.25 miles, what number of inches on the map represent 10 actual miles	14,381	3	[]
volunteer	So 3in = 1.25 and ?in=10 miles	14,381	4	[]
volunteer	Correct?	14,381	5	[]
student	Yes	14,381	6	[]
volunteer	Okay first we need to find out how many miles is in one inch	14,381	7	[]
volunteer	Do you know how to do that	14,381	8	[]
student	Do we divide?	14,381	9	[]
volunteer	Correct!!	14,381	10	[]
volunteer	Which numbers though because we're given 3 different numbers	14,381	11	[]
student	Maybe 3 and 1.25?	14,381	12	[]
volunteer	Exactly! So go ahead and divide 3/1.25	14,381	13	[]
volunteer	1.25/3 is what I meant!	14,381	14	[]
student	0.416	14,381	15	[]
