Write the slope Intercept form of the depletion of the line that contains -4,6 and 6,-1

Slope intercept form: y = mx + b

Slope m = ( y2 - y1) / (x2 - x1)
Once you find m, substitute that into
y = mx + b. Then use one of the two given points and substitute them into the previous equation. This will enable you to solve for b.
