What is an equation for the line that passes through points (–1, –4) and (1, 4)? Write the equation in slopeintercept form.
the most I know is that I believe you use the formula y=mx+b
I just have trouble actually solving it. Help please and thank you?

you cant use y=mx+b because you dont know b (y intercept)

First you need to find the slope. Here is the formula: dw:1352307856268:dw then you plug the slope you found into y=mx+b, m being the slope, along with either point from the problem as x and y. Solve for b. Once you've found b, plug both b and the slope in y =mx +b and you have your answer.
