Pls help I don’t understand

y = 3x + -3

In the equation

y = _x + _

There asking what does "y" equal.

So if we look at the "y axis" we can see that the line passes through the 3.

Next, we need to find "x" if we look at where the line meets the graph on the "x" axis we can see that it lands on -3.

  Thus, y = 3x + -3 is your answer.
