Question

Find the slope of the line that passes through (1,8) and (-3,12)

Answer 1

Given:

The given points are (1,8) and ( -3,12).

Required:

We need to find the slope of the line that passes through (1,8) and (-3,12).

Step-by-step explanation:

Consider the sope formula.

`Slope=(y_2-y_1)/(x_2-x_1)`
`Substitute\text{ }y_2=12,y_1=8,x_2=-3,\text{ and }x_1=1\text{ in the formula,}`

`Slope=(12-8)/(-3-1)`

`Slope=(4)/(-4)`
`Slope=-1`

Final answer:

The slope of the line is -1 that passes through (1,8) and (-3,12).
