Is the answer 4/5 ? Can someone help please ?

Zina [86]

Answer:

$m=-\frac{4}{5}$

Step-by-step explanation:

We can take 2 arbitrary points in the graph and solve for slope using the formula shown below.

<u>Note:</u> we will use the 2 points (2,-3) & (-3,1)

Where x_1 = 2, y _1 = -3 and x _ 2 = -3 and y _ 2 = 1

The formula:

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

Let's plug the numbers and find the slope:

$m=\frac{1-(-3)}{-3-2}\\m=\frac{4}{-5}\\m=-\frac{4}{5}$

Hence, thsi is the slope.
