Hi dear,
if the straight line passes through the points (-2,1) and (3,-2)
Then,the formula below will be used to solve for the equation of the line.

where y1=1,y2=-2,x1=-2,x2=3.
substitute the above in the given formula
Therefore,
(y-1)(3+2)=(x+2)(-2-1)
5(y-1)=-3(x+2)
5y-5=3x+6
5y=3x+11

determine the equation of the straight line through the points (-2,1) and (3,-2)
=================
Step 1m find the slope
Slope m = diffy.diffx = (-2-1)/(3- -2) = -3/5
-----------
Then use y-y1 = m*(x-x1) where (x1,y1) is either point.
---
y-1 = (-3/5)*(x+2)
