Answer: -2
Explanation:
- Step 1) Start at 1 on the horizontal x axis number line.
- Step 2) Draw a vertical line straight down until you reach point P that is marked in the attached image (see below). Point P is on the diagonal line.
- Step 3) From point P, move horizontally until you reach -2 on the vertical y axis number line.
We started with x = 1 and ended up with y = -2. So the point (x,y) = (1,-2) is on the diagonal line. In other words, point P is located at (1,-2).
