To answer this question, locate the value -1 on the horizontal line labeled x. Follow the vertical line through that point down until it reaches the curve. (There is a convenient dot on the curve at that point.)
Then, follow the horizontal line to the right to see what the y-value is for that dot. Here, it is -2. This means ...
... the value of y when x is equal to -1 is ...
... -2 . . . . . . . . the third choice
