Question

What is the slope of the line through (-1,8) and (3, -4)?

Answer 1

Answer:

Step-by-step explanation:

$slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-4-8}{3-(-1)}\\\\=\frac{-12}{3+1}\\\\=\frac{-12}{4}\\\\=-3$

Answer 2

Answer:

-3

Step-by-step explanation:

The slope of a line is the ratio of the vertical distance and horizontal distance between two points on a line.

Note that zero is tangible if the line is horizontal, and undefined if it is vertical.

Slope = ∆y / ∆x

Coordinates given: (-1,8) and (3,-4)?

Slope = -4 - 8 / 3 - (-1)

Slope = -12 / 4

= - 3
