determine the equation of the line in y=mx+b form that passes through

1. (-8,1) & (-9, 2)

2. (3,7) & (-5, 9)

3, (-4,0) & (4,6)

Part B ) For each equation

Rewreite the y=mx+b equation in general form Ax+by+c=0 where A is positive b and C are integers

In each problem, put in x,y for each point set to get two equations to solve m,b

For example, in the first...

1=-8m+b and

2=-9m+b

solve these In this case subtract the bottom equation from the top

-1=m then solve for b.

k tnx
