Question

2 Points
What is the slope of the line shown below
(3,9)
(1,1)

Answer 1

ANSWER

The slope is 4

EXPLANATION

We want to find the slope of the line goin through (3,9) and (1,1)

We use the slope formula:

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

We substitute the points into the slope formula to get;

$m = \frac{1 - 9}{1 - 3}$

This simplifies to:

$m = \frac{ - 8}{ - 2}$

$m = 4$

Hence the slope of the line is 4.
