Question

Find the slope of the line going through the points (-4, 13) and (8,-11).

Answer 1

Slope = -2

Explanation:

`\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=(y_2-y_1)/(x_2-x_1)\\\\left(x_1,\:y_1\right)=\left(-4,\:13\right),\:\left(x_2,\:y_2\right)=\left(8,\:-11\right)\\m=(-11-13)/(8-\left(-4\right))\\\mathrm{Refine}\\m=-2`

Answer 2

The Slope is -2

Explanation:

The entered points belong to a decreasing, linear function.

Equation: y = -2x + 5.
