Question

Complete the equation of the line through (2,1) and (5,-8) in y=Mx+b form

Answer 1

y=-3x+7

Explanation:

find the slope which is (y1-y2)/(x2-x1). therefore the slope is -3. and then put it in point slope intercept form which is (y-y1)=m(x-x1) = (y-1)=-3(x-2) and simplified the expression is y=-3x+7.
