David's score on his fifth test would be an 87. If you add up all the scores from his first to his fourth test, it would 363. However, since there are five tests, in order to get a 90 percent, the sum of all five test scores would be 450. 450 - 363 = 87.
The answer for the exercise is the third option, which is: Hexagon.
The explanation is shown below:

Answer:

Step-by-step explanation:
The inverse of a slope is the exact opposite slope of the original. I'll show a function below where you can easily solve future problems if you need to.

m is the slope, so for the equation above, you simply insert the original slope, being 1, in the equation.

So the inverse slope would be -1.
