Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
y = x + 5 → (1)
x - 5y = - 9 → (2)
Substitute y = x + 5 into (2)
x - 5(x + 5) = - 9 ← distribute and simplify left side
x - 5x - 25 = - 9
- 4x - 25 = - 9 ( add 25 to both sides )
- 4x = 16 ( divide both sides by - 4 )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = - 4 + 5 = 1
Solution is (- 4, 1 )

We need to find the midpoint. Let's call the midpoint M where M = (x,y). For now x and y are unknown
To find the x coordinate of the midpoint, we add up 5 and -1 (which are the x coordinates of E and F respectively) and divide by 2
So 5+(-1) = 5-1 = 4 which divided over 2 is 4/2 = 2
The x coordinate of the midpoint is x = 2
Similarly, the y coordinate of M is y = (-2+3)/2 = 1/2 = 0.5
So the midpoint M is (x,y) = (2, 0.5)
One property of M is that EM = MF. Another property is that EM+MF = EF
