Question

what is an equation for the line that passes through points (-1 -4) and (1, 4) please help; I never get any help here

Answer 1

do you know formula to find slope ??

Answer 2

nope :/

Answer 3

okay np :)

Answer 4

formula is \[\huge\rm m = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1}}\]
now you have to order pair where \[\huge(x _{1}, y _{1} ) (x _{2} , y _{2})\]
now replace variables by their values

Answer 5

(-1one,y-4) (1two, 4two) ?

Answer 6

yes right :) now use formula
replace variables by their values
