    What ones do you think are correct? Just plug them into the equation and see if it is true or no

    f(x) = 3 - 2x Lets try this point (-2, -1) -1 = 3 - 2(-2) -1 = 3 - 2(-2) -1 = 3 + 4 -1 = 7 Since -1 = 7 it is false and is not a solution.

    I took the equation f(x) = 3 - 2x and then I used the point, which is the first point you have (-2, -1) -2 is in the x position and -1 is in the y position. f() = y position and x where you see 2x = x position. take the x and y of the point (-2,-1) and plug it into your equation and solve like I did but do it with the rest of the points.
