Question

The slope of the line that passes through the points (1,8) and (3,12), is:
6
2
3
1

Answer 1

Step-by-step explanation:

If the coordinates, (x, y), of two distinct points which lie on a straight line are known, then, consequently, the slope, m, of the line can be found by using the following equation:

slope m = rise/run

m = (a change in y)/(a change in x)

m = Δy/Δx

m = (y₂ - y₁)/(x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are two known points on the line whose slope is to be determined.

Let (x₁, y₁) = (-8, -1) and let (x₂, y₂) = (-6, -2).

Substituting these coordinates into our equation, we get:

m = (-2 - (-1))/(-6 - (-8))

m = (-2 + 1)/(-6 + 8)

m = (-1)/(2)

m = -1/2 is the slope of the line which passes through points (-8, -1) and (-6, -2).
