graph y=-(1/2)x+1, (4,2) with steps to solve
y = -(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
joint the two points and there is your line.
