Answer:
The answer to your question is:
5) slope = 0
6) slope = 0.7
7) slope = 0.04
8) slope = 21.7
Explanation:
Slope is the tangent of the angle form between a line and the x-axis.
So
15)
there is no slope, then m = 0
16)
Here we have the legs of a right triangle so we can find the tangent
tangent = opposite leg / adjacent leg
tangent = 70 / 100 = 0.7
17)
Also here, we can imagine a right triangle
tangent = 15 / 384 = 0.04
18) Also here we have a right triangle
tangent = 13000 / 600 = 21.7
