Question

What is the slope of the line that passes through the pair of points? (1, 7), (10, 1)

Answer 1

The slope of the line can be calculated as:

(1-7) / (10-1) = -6 / 9 = -2/3

Answer 2

M (Slope of a line) = y2 - y1 / x2 - x1

Plug in the points accordingly.

M = 1 - 7 / 10 - 1
M = -6 / 9
M = -2 / 3  (simplified)

Therefore M = -2/3
