  1. Model the function rule y = -2x - 3 with a table of values. Show your work.

    14. For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept.

  1. to make our table, we sub in any value for x and solve for y

    y = -2x - 3

    lets say x = 0
    y = -2(0) - 3
    y = -3....so when x = 0, y = -3

    lets say x = 1
    y = -2(1) - 3
    y = -2 - 3
    y = -5...so when x = 1, y = -5

    lets say x = 2
    y = -2(2) - 3
    y = -4 - 3
    y = -7....so when x = 2, y = -7

    so ur table will look like this...

    x           0         1          2
    ----
    y          -3         -5         -7

    u can find more points if u need to by just repeating the steps I did

    14. to find the x intercept, sub in 0 for y and solve for x

    y = -2x - 3
    0 = -2x - 3
    2x = -3
    x = -3/2...so the x intercept is (-3/2,0)

    to find the y intercept, sub in 0 for x and solve for y

    y = -2x - 3
    y = -2(0) - 3
    y = -3....so ur y intercept is (0,-3)
