Write the point-slope form of an equation of the line through the points (-4, 7) and (5, -3).

--------------------------------------------------------
Write the point-slope form of an equation of the line through the points (h, k) and (p, v).
-----------------------------------------------------------

Slope for the two given points, %28v-k%29%2F%28p-h%29

Picking point (h,k), and variable point (x,y),
%28y-k%29%2F%28x-h%29=%28v-k%29%2F%28p-h%29

highlight%28y-k=%28%28v-k%29%2F%28p-h%29%29%28x-h%29%29

Just plug in the numbers given for your specific example. Simplify your slope.
