Answer: c because the y intercept is the only correct one, not only that, if you plug in 4 as x in the equation, the y value would be -2 and that ordered pair fits on the line in the graph
Step-by-step explanation:

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
To obtain vertex form from the given equation use the method of completing the square
given 8y + x² = - y² - 181 + 26x
rearrange having the x terms and y terms together
add y² to both sides
8y + x² + y² = - 181 + 26x ( subtract 26x from both sides )
x² - 26x + y² + 8y = - 181
add (half the coefficient of the x/y terms )² to both sides
x² + 2(- 13)x + 169 +y² + 2(4)y + 16 = - 181 + 169 + 16
completing the square on both the x and y terms
(x - 13)² + (y + 4)² = 4 → D
343 is the answer because 14 tens is 1 hundred and 4 tens
