Question

What is slope of line between each pair of points?
(1, -19) and (-2, -7)

Answer 1

The slope of the line is $m=-4$

Explanation:

Given that the pair of points are $(1,-19)$ and $(-2,-7)$

We need to determine the slope of the line.

The slope of the line can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the points $(1,-19)$ and $(-2,-7)$ for the coordinates $(x_1,y_1)$ and $(x_2,y_2)$ in the above formula, we have,

$m=\frac{-7-(-19)}{-2-1}$

Simplifying the terms, we get,

$m=\frac{-7+19}{-2-1}$

Adding the terms, we have,

$m=\frac{12}{-3}$

Dividing, we get,

$m=-4$

Thus, the slope of the line between the pair of points is $m=-4$
