Answer:
3x + 5y = 11 -> y = -3/5x + 11/5
9x + 15y = 33 -> y = -3/5x + 11/5
The midpoint would be (7, 5)
The midpoint of any two points is simply the average of the x points and the average of the y points. So we'll start by averaging the 2 x points together. To take an average, we add the two numbers together and divide by 2.
X VALUE
4 + 10 = 14
14/2 = 7
Now do the same for y
Y VALUE
22 + -12 = 10
10/2 = 5
Using those answers we can create the ordered pair (7, 5)
