SOLUTION: Show that the equation of the line that passes through the points (0,b) and (-1,b-m) is y=mx+b. Explain how you can be sure that the point (-1,b-m) also lies on the line.

(0,b) and
(-1,b-m) m =%28y%5B1%5D+-+y%5B2%5D%29%2F%28x%5B1%5D+-+x%5B2%5D+%29 slope = m/1
***Using point-slope form, y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29P(0,b)
y - b = m(x-0)
y = mx + b
