Write an equation for the line with the given slpe that contains the given point. Graph each line.
1. slope 2,(2,-2)
So take the slope-intercept equation: y=mx+b and plug in the known values.
You know the slope (m), so it becomes: y=2x+b
You are also given a point on the graph (x,y)
-2=2(2)+b
Solve for b.
-2=4+b
-2-4=b
-6=b
So therefore, y=2x-6
