(y - Y1)____ (Y2 - Y1)
--------- = ---------
(x - X1)____ (X2 - X1)
means
(y - 7)/(x+5) = (-3 -7)/(-4 + 5)
or
(y - 7)/(x+5) = -10/1 = -10
Write an equation for the line, in point-slope form, that passes through the points (-5, 7) and (-4, -3). Use (-5, 7) as the point (x1,y1)
So far I got Y- 7=-1/9(X + -5)
