<h3>
Answer: D. (2, 21)</h3>
Explanation:
Imagine that your teacher wanted you to find the midpoint of -3 and 7 on the number line. To do this, you would add up the given values and divide by 2.
(-3+7)/2 = 4/2 = 2
The value 2 is right in the middle of -3 and 7 on the number line. This result is also the x coordinate of the midpoint since the values I used were the x coordinates of the original points.
The y coordinates are handled the same way:
(18+24)/2 = 42/2 = 21
The y coordinate of the midpoint is y = 21
Overall, the midpoint is (2, 21)

Step-by-step explanation:
hope this helps :)
The phase shift is the value of the angle when the variable
in the angle is zero.
The angle in the sin function in this equation is (pi X + 2).
When the variable 'X' is zero, the angle is 2 .
So the phase shift of this sin function is 2 (of whatever
the unit of the angle is ... 2 degrees, 2 radians, etc.)
