Step-by-step explanation:
So for questions 1 through 4, you're basically finding the number in the middle of the two letters. In question 1, D is above 7 on the number line and E is above 11. The mid-point would be 9.
For 5 and 6, we'll be using this formula: [tex](\frac{x_{1} + x_{2}}{2},\frac{y_{1} + y_{2}}{2})[/tex]
And now we just plug in the numbers from question 5 but it works the same way on 6 as well.
[tex](\frac{3 + 5}{2},\frac{1 + 3}{2})[/tex] => (8/2, 4/2)
Coordinate of the midpoint would be (4, 2).
Lastly, we follow this system in order to get the final answers:
(Answer below shown for question 7)
(x + 2)/2 = 5
x + 2 = 10
x = 8
(y + 0)/2 = 2
y + 0 = 4
y = 4
Missing endpoint is (8, 4)
