Question

Find the slope of the line that passes through the origin and (8, -5).

Answer 1

use slope formula:
\[\frac{ y_1-y_2 }{ x_1-x_2 }\]

Answer 2

so we have 2 points: (8, -5) and (0, 0)

Answer 3

but how?

Answer 4

substitute them and solve

Answer 5

oooh

Answer 6

(0, 0) is an orgin

Answer 7

the formula @AlexandervonHumboldt2 wrote out can be thought of this way

step 1) subtract the y coordinates
step 2) subtract the x coordinates (same order as step 1)
step 3) divide the y difference over the x difference to get the slope

Answer 8

-5/8

Answer 9

yes correct
