<h3>
<u>Explanation</u></h3>

The structure or equation is similar to a quadratic function.
The value of a determines the slope of graph.
Tthe value of h determines the horizontal shift of graph.
The value of k determines the vertical shift of the graph.
From the given equation,

We can say that the graph shifts to the right 2 units and shifts down 7 units. Hence the vertex would be at x = 2 and y = -7. It can be written in coordinate form as (2,-7).

Answer:
(1,5)
Step-by-step explanation:
You use the midpoint formula to solve this problem
The midpoint formula:
To solve for x: (x1+x2)÷2
To solve for y: (y1+y2)÷2
Answer:
y = 2x - 9
Step-by-step explanation:
y= mx + b
plug in slope
y = 2x + b
plug in points
1 = 2 (5) + b
simplify
1 = 10 + b
subtract 10 each side
-9 = b
plug in to original equation
y=2x - 9
