 Question 251016: If a line contains the point (0, -1) and has a slope of 2, then which of the following points also lies on the line? (2, 1) (1, 1) (0, 1) Answer by richwmiller(9135)   (Show Source): You can put this solution on YOUR website!y=mx+b with a slope of 2 we now have y=2x+b since the point is (0,-1) we plug them in and solve for b -1=2(0)+b -1=b so now we have y=2x-1 so now we just plug in the ordered pairs to see which give equalities (2, 1) y=2x-1 1=2*2-1 1=4-1 1=3 not on the line (1, 1) y=2x-1 1=2*1-1 1=2-1 1=1 yes on the line (0, 1) y=2x-1 1=2*0-1 1=-1 not on the line
