Answer:
The vertex is the point 
Step-by-step explanation:
we know that
The general form of an absolute value equation is

The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables h, and k, tell us how far the graph shifts horizontally and vertically
The vertex is the point (h,k)
we have

Rewrite the expression (3x+1)

substitute



therefore
The vertex is the point

Answer:
6750:9000*100 =
(6750*100):9000 =
675000:9000 = 75
Now we have: 6750 is what percent of 9000 = 75
Question: 6750 is what percent of 9000?
Percentage solution with steps:
Step 1: We make the assumption that 9000 is 100% since it is our output value.

Y=-7
When a slope is zero the line will be vertical so basically all you need to do is get the Y of your points and use that in your sub intercept equation
It’s 5 since you’d use Pythagorean theorem
