If you graphed the equation: y = 5
You would put a straight line going horizontally through 5. Like this picture shows. If it were x = 5, for example, then it would go up and down through 5.
Let me know if this helped! Have a nice day!
To graph the equation y = 5, we must know what horizontal lines are. Horizontal lines are lines that are written in the form y = c, with y being the variable y and c being a constant. The c represents at which y value the horizontal line will form. That means that in this case, the horizontal line will be at the 5 value of y. Now we have to graph a horizontal line at 5. Doing this gives us:

Answer:
(x - 11)² + y² = 25
Step-by-step explanation:
First find the center
O = ( (15 +7 / 2), (-3 + 3)/2 )
O = (11, 0)
Then find the radius squared
use the distance formula from the center to either end point of the diameter
r² = (15 - 11)² + (-3 - 0)²
r² = 16 + 9
r² = 25
Formula for circle
(x - h)² + (y - k)² = r²
(h, k) is the center = (11, 0)
The equation is
(x - 11)² + y² = 25
