# What is the slope of the line passing through the following points:  (8,10), (1, 3)?

Feb 8, 2016

The formula for slope is $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

#### Explanation:

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

The points $\left({x}_{1} , {y}_{1}\right)$ and #(x_2, y_2) are interchangeable.

$m = \frac{3 - 10}{1 - 8}$

$m = - \frac{7}{-} 7$

$m = 1$

The line's slope is of 1.

Practice exercises:

1. Find the slope separating the points (2, -5) and (-4, -7)

2 . The following graph is of a linear function. Find its slope.

graph{y = -2/3x - 1 [-10, 10, -5, 5]}

Good luck!
