Vertical lines have undefined slope. They are not y=mx+b equations, but simply x= equations.

This line passes through the point (-1,12) has an x-value of -1. Therefore the equation of the line is simply x=-1

Simplify: (-3x^3+2x^2+4x)-(8x^4-5x^3+6x^2-2x

Answer:

−8^4+2^3−4^2+6

Step-by-step explanation:

Distribute the - to 8x^4-5x^3+6x^2-2x:

-8x^4+5x^3-6x^2+2x

Now simplify:

-3x^3+2x^2+4x-8x^4+5x^3-6x^2+2x= −8^4+2^3−4^2+6

Hope this helps!
