Find the function g, given that g is linear, the graph of g has y-intercept -2. And g(1) =5.

  • math - ,

    so you have a slope of -2 and a point (1,5)

    y = -2x + b
    plug in the point
    5 = -2(1) + b
    b = 7

    y = -2x + 7

    or

    y-5 = -2(x-1)
    y-5 = -2x + 2
    y = -2x +7
