Do you mind if you guys me with this question i’m on number 8

An equation in slope-intersept form the lines that passes thought (-8,1) and is perpindicular to the y=2x-17.

3questions show how you solved the problem 1. subtract & simplify (–y2 – 4y – 8) – (–4y2 – 6y + 3) 2.multiply and simplify 2x2y3z2 · 4xy4x2 3.multiply and simplify (x – 4) (x2 – 5x – 6)
