Answer:
23
Step-by-step explanation:
I'm going to start by solving the first equation like so,
y - 8 = 15 (Remember what we do to one side we MUST do to the other)
<u> +8 +8 </u>
y = 23
So know we know y = 23 What we have to do now is replace 23 for y in the second equation.
y - 0 = ?
23 - 0 = 23
Hope that helps and have a great day!
Answer: A horizontal translation 2 units to the left
In this case, we are changing the variable x before it is being squared. This will have the effect of changing the input of the function. Imagine input 2 into the equation. Your first step would be to add 2. Therefore, you would need to start with a negative 2 to get us back to 0, or the beginning.
Since -2 is to the left of 0, the graph is moving 2 units to the left.

Answer:
The answer is y=-x+9.
The first thing to do is find where the line intercepts the y-axis, which is at positive 9 so you'll add a +9 to the end of your equation. Next you find the slope and since it's going down left to right, you know it is a negative. Now slope is found by change in y divided by change in x. And since both change and y and change in x are both 1, 1/1 is 1. And since you know it's negative that means the slope is -x. Altogether you get y= -x+9
