How do i work this problem out using the equation a=pe^rt

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

Me! i will mark brainliest! i don't get polynomials and all that other stuff. so this question is really hard. multiply and simplify.(x - 4) (x^2 – 5x – 6)show your
