graph y=-(1/2)x+1, (4,2) with steps to solve

  • college algebra -

    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
    (4,-1)
    joint the two points and there is your line.
