Question

what is an equation for the line that passes through points (-1,-4) and (1,4)

Answer 1

first you need to find the slope. do you know how to do that?

Answer 2

i know it has something to do with being set up (x1,y1) (x2,y2) right?

Answer 3

yes the point slope eqn is (y2-y1)/(x2-x1)

that'll give you your slope to plug into y=mx+b

then just use one of the (x,y) points to solve for b

gotta go to class hope i could help

Answer 4

okay thank you ill see if i can figure it out

Answer 5

if not ill be back on in about 2hrs

Answer 6
