The formula is (x1+x2)/2 will give you the x of the mid point.
(y1+y2)/2 will give you the y of the mid point.
So, (3+9)/2= 6
And (6+8)/2=7
The mid point is (6:7)
Answer:
a) y = 6x - 3
b) 1/3y = 2x -1
The first thing you need to do is isolate (y) in the second equation
3 x (1/3y) = 3 x (2x - 1)
y =6x - 3
After isolating (y) in equation b they end up being the same.
Graphing:
In order to graph this, you have to make the first point at (0, -3) since this is the Y-intercept of the equation.
In order to graph the other points, you must move 6 units up and 1 unit to the right. Or vise versa If you need a visual I'll gladly link one.

Step-by-step explanation:
We want to find what we need to mix to get 10 cups of lemonade.
We need to use 2 cups of lemon juice and 8 cups of water to get a total of 10 cups of lemonade.
We know that the lemonade recipe is:
1 cup of lemon juice and 4 cups of water.
This gives us a total of:
1 cup + 4 cups = 5 cups of lemonade.
Then if we want 10 cups of lemonade, we just need to use the double of each one of the ingredients.
this is:
2*(1 cup) = 2 cups of lemon juice
2*(4 cups) = 8 cups of water.
We need to use 2 cups of lemon juice and 8 cups of water to get a total of 10 cups of lemonade.
