Please let me know if I figured this out correctly.
Directions:Write an equation for the line that is perpendicular to the given line and that passes through the given point.
1) y=x3; (4,6) Answer: y=x10
Thank you!

no, (4,6) does not satisfy your new equation.
The new equation has to be
y = x + b, but (4,6) lies on it, so
6 = 4 + b
b = 10
new equation is
y = x + 10
