Answer:
(-3,-10)
Step-by-step explanation:
Given part a, you seem to know the midpoint formula. We can easily edit that to figure out what an endpoint is. Say that a variable "a" represents the x coordinate of D, and b the y coordinate. As the x coordinate of M is 0.5, and the x coordinate of C is 2, we can use the midpoint formula to say that . Multiplying both side by 2, we get that a+2=-1, and subtracting both sides by 2, a=-3. Similarly,
, b+7=-3, and b=-10, making our answer (-3, -10). Let me know if you have any questions.
