That's a quarter of the circle. So find the area of the circle, and divide by 4 to get the answer.

Circle area = 3.14*13^2 = 530.66
Answer = circle area / 4 = 132.665

Which line is a graph of the equation: 2x + 5y = -10?
Lady bird [3.3K]

Answer:

D

Step-by-step explanation:

2x + 5y = - 10         Subtract 2x from both sides

5y = -2x - 10           Divide by 5

y = -2x/5 - 10/5      

y = 0.4x - 2

The slope is minus so the line is going from lower right to upper left as B and D are doing.

The y intercept is - 2. B goes through + 2 so it is not the answer.

The answer is D
