Question

which is steeper, a line with a slope of 7 or a line with a slope of -10? Can you explain it to me also?

Answer 1

The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.

Thus, even though it is decreasing, the greater change is the -10.
