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

12/5

Step-by-step explanation:

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

`m=(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=(20-(-4))/(9-(-1))=(20+4)/(9+1)=(24)/(10)=(12)/(5)`
