Question

A line crosses the x-axis at -7 and the y axis at 10. Is the slope of the line positive or negative?

Answer 1

The slope is positive.

Explanation:

With the line crossing over at -7 on the x-axis and 10 crossing over on the y-axis, you're able to form the two points. (-7, 0) & (0, 10).
0 - -7 = 7 & 10 - 0 = 10, so you get 10/7

The slope will be y = 10/7x + 10, therefore it's positive.

Answer 2

The line is positive

The line is positive because it slants to the right.

It wouldve been negative if it slanted to the left.
