Question

help please? Find the slope of the line containing the points (1,4) and (-2, -5). Enter your answer as a fraction or decimal. (The answer is 3, but I can't figure out how they got it.)

Answer 1

Using the first point as \((x_1,y_1)\)

Answer 2

Sorry, flip the first fraction. Correcting now.

Answer 3

\[\frac{y_2-y_1}{x_2-x_1}\]

Answer 4

Do you understand how to set up the formula?

Answer 5

so -2-1/-5-4?

Answer 6

Flip the fraction. Change in y should be on top. Change in x should be on the bottom.
