Question

what is an equation for the line that passes through points (-1 -4) and (1, 4)? Write the equation in slope-intercept form

Answer 1

\[y-y_{1}=m(x-x_{1})\] just plug it in.

Answer 2

First find the slope \[m = \frac{ y_2-y_1 }{ x_2 - x_1 }\]
then plug into the formula zephyr gave

Answer 3

idk what goes were...

Answer 4

you were given two points,
(x1, y1) and (x2, y2) which are
(-1 -4) and (1, 4)

so plug those into the slope formula

Answer 5

4^2--(4) / 1-(-1)

Answer 6

correct, but you have a ^2 there which should not be
