Question

Find the slope, or rate of change, from the following ordered pair: (-2, 17) and (-1,5)

Answer 1

Slope, m = -12

Explanation:

Given the following data;

Points on the x-axis (x1, x2) = (-2, -1)

Points on the y-axis (y1, y2) = (17, 5)

To find the slope, m;

Mathematically, slope is given by the formula;

`Slope = (Change \; in \; y \; axis)/(Change \; in \; x \; axis)`

`Slope, m = \frac {y_(2) - y_(1)}{x_(2) - x_(1)}`

Substituting into the equation, we have;

`Slope, m = \frac {5 - 17}{-1 - (-2)}`

`Slope, m = \frac {-12}{-1 + 2}`

`Slope, m = \frac {-12}{1}`

Slope, m = -12
