Answer 1

The slope of the line passing through the points (-1, 3) and (4, -7) is -2.

Explanation:

Use the slope formula that states:

m = (y₂ - y₁)/(x₂ - x₁)

Substitute variables.

m = (-7 - 3)/(4 - (-1))

Subtract -7 and -3.

m = (-10)/(4 - (-1))

Subtract 4 and -1. When subtracting a negative, add.

m = (-10)/5

Divide -10 by 5.

m = -2
