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
