When 2 points are given, you would use the point slope formula. y-yo = m(x-xo). You may also use a different formula. P1 (x , y) and P2 (z , h)
then slope of line = ( h - y)/ (z - x)
so, apply this formula here also
slope of line = (-1-2)/(7- {-3})
(-3)/(10)
Where yo = either of the 2 point y coordinates
xo = either of the 2 point x coordinates (paired with the above point)
m = the slope
In this case, m = (-1-2)/(7+3) = -3/10
Using point 1,
y-2 = (-3/10)(x+3) = (-3/10)x -9/10 or y = (-3/10)x + 11/10
