 Question 136303: I have two sets of points; (42,20) and (52,10). I need an equation in the form of y = mx + b. The answer I got was y = 1x - 22. Is this correct?Answer by scott8148(6628)   (Show Source): You can put this solution on YOUR website!no __ as x increases from 42 to 52, y decreases from 20 to 10 you have the right number for the slope, but the wrong sign this leads to an intercept (b) of 62 y=-x+62
