The rules about opositive and negative numbers include
- Two like signs become a positive sign
- Two unlike signs become a negative sign
<h3>How to illustrate the information?</h3>
It should be noted that two like signs become a positive sign. For example, (-2) × (-4) will be:
= (-2) × (-4).
= +8
Two unlike signs become a negative sign. This will be:
(-2) × (+4)
= -8

Answer:
(17,0) and (-2,19)
Step-by-step explanation:
First, find the gradient of AB, which is 1. As CD is perpendicular, its gradient will be -1. The equation of CD will be y=17-x. The x intercept is where y=0. So, that will give you x=17. When x=-2, y=19. It proves the equation right.
