**Reiny**, Thursday, May 16, 2013 at 8:02amy = -(1/2)x + 1 is a straight line with slope -1/2 and y-intercept of 1

(4,2) is a point that does NOT lie on this line.

What are you "solving" for ?

To graph the line, use the y-intercept of (0,1) and any other point,

e.g. let x = 4

y = (-1/2)(4) + 1 = -1, so another point would be

(4,-1)

joint the two points and there is your line.
