Answer:
(-1,-18) is the coordinate of the vertex.
Step-by-step explanation:
We can obtain the vertex by taking the derivative and equating it to zero. I know this because the the slope of the tangent line at the vertex has to be equal to zero.
the derivative would be 4x + 4 = 0, where x = -1.
Plugging x into the original value we will end up with the y coordinate.
Hope this helps.

Answer:
Option 1: y + 5 = ½(x - 2)
Step-by-step explanation:
First, you need to find the slope. the formula to find the slope from two points is
and if you plug in the points it will be
which is
.
point-slope form is
. m is slope and x₁ and y₁ is (2, -5).
plugging in the numbers will be y + 5 = ½(x - 2)
