Answer:

c) y=\frac{2}{3} x+9

Step-by-step explanation:

The way I solve these is...

First, you look at where the line crosses the y-axis because that's your b in the y=mx+b equation. Which is 9

Then I find a point where the line passes thru so for example, (-6,5) Remember that x point is always before the y.

From there I determine if the line is positive or negative, this one's positive because the line goes up from left to right, if it were going up from right to left, then it'd be negative.

So knowing it's positive we count the points up and to the right until reaching the next point. So first go up 2 points and then right 3.

Knowing this, remember that it's always rise over run for the slope, so we rose 2, and ran 3. so, the slope is 2/3

This gives us our equation of y=\frac{2}{3} x+9

What is the vertex of the function f(x) = x2 + 12x?
Sophie [7]
We can start by figuring out the axis of symmetry.

y = x² + 12x = x (x + 12)

So roots are x = -12 or 0

Therefore axis of symmetry is x   =   (-12 + 0) / 2   =   -6

We got x-coordinate of vertex. Now plug in x=-6 to solve for y.

y = (-6)² + 12(-6)   =   36 - 72   =   -36

Therefore vertex is (-6, -36).
