Question

Find the slope of the line that goes through the points (-1,-4) and (9, 20). You must show all of your work in the space provided.

Answer 1

Answer:

12/5

Explanation:

To find the slope of the line, we'll need to use the below formula;

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

where x1 = -1, y1 = -4, x2 = 9, y2 = 20, so let's go ahead and substitute these values into our formula and solve for m;

$m=\frac{20-(-4)}{9-(-1)}=\frac{20+4}{9+1}=\frac{24}{10}=\frac{12}{5}$
