Find the y value at the point x = -2.

By looking at the graph, we can visually determine that the value of y when point x = -2 is -4.

-4

Step-by-step explanation:

The y value at x=-2 is -4 because when you go to -2 on the x-axis the function is below there.  You can only go straight up or straight down to determine the y-value that corresponds to x=-2 so we go down because the function is below the x-axis there.

We are going to go down until we get on the graph of the line.  Scroll over with eyeballs to see that the y there is -4 (use the y-axis).

So the ordered pair (-2,-4) is on our line and when x=-2, y=-4.

Another example:

y=0 when x=2

Another example:

y=2 when x=4

Another example:

y=-3 when x=-1
