D: y=3x-2

The reason why this equation works is because when we plug in x-values into it, we get the written y-values. Lets try using -3 for x and see if we get -11. y=3(-3)-2 y=-9-2 y=-11 Yes we do get -11 as our y-value. Even when we try all of the x-values in the table, we get their y-values so therefore this is the correct equation.
