Question

The equation of the normal line

Answer 1

Answer:

D. y = 1/2x + 3/2

Explanation:

You probably already know the point slope equation:

y = m(x - x₀) + y₀

All you need is the slope and the (x₀, y₀).

The (x₀, y₀) could be solved by plugging in the given x=-1 value into the function.

m, the slope, is the same as a derivative; ie. a derivative is a slope.

So solve for the derivative and find the slope at x=-1.

Plug into point slope equation and simplify.
