You would need to find the slope of the line and the intercept first.
To find the slope, you can use the formula m=(y₂-y₁) / (x₂-x₁).
m= (6-4) / (-5-1)
m= 2/-6
The slope then simplifies down to -1/3.

In screen coordinate system i.e top left corner = (0,0) and bottom right corner = (800,600), How can we find the equation of a line given ?
Also how the intersection point of this line can be calculated with the screen boundary ?
I think you mean {0,0} to {799,599}.

9828 = 2233713
9828 has 48 divisors (see below), whose sum is σ = 31360. Its totient is φ = 2592.
The previous prime is 9817. The next prime is 9829. The reversal of 9828 is 8289.
Subtracting from 9828 its sum of digits (27), we obtain a square (9801 = 992).
Multipling 9828 by its sum of digits (27)... | HuggingFaceTB/finemath | |
