Question

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

Answer 1

-3

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

Answer 2

Explanation:

`slope=(y_(2)-y_(1))/(x_(2)-x_(1))\\\\=(-4-8)/(3-(-1))\\\\=(-12)/(3+1)\\\\=(-12)/(4)\\\\=-3`
