Answer:

Step-by-step explanation:
The total number of squares is 36, and only 6 of them are shaded therefore, the remaining 30 are not shaded. The probability that a randomly selected square is not shaded would therefore be:

4 - 1/x (16)-1/x 2
4x-18/x
Answer: Pick the graph that hits each of these points (-2, -18) (-1, -6) (0, -2)
(This graph should be on the horizontal line, then start to move downand to the left) Hope this helps!
