Question

Pls help fasttttttttttt

Answer 1

Explanation:

(3, 4), (2,7)

`(x_(1) ,y_(1) ),(x_(2) ,y_(2))`

slope = m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )` =
`(7-4)/(2-3)` =
`(3)/(-1)` = -3

She makes an error with the formula for finding the slope.

Answer 2

the formula to finding the slope is :

`(y2-y1)/(x2-x1)`

you can reverse it so that its y1 - y2/x1 -x2 but top and bottom must always be in the same order

the classmate's answer should have been 4-7/3-2 which would equal -3/1 = -3
