4x + 8(3x-7) = 22x -65 distributive property
4x +24x -56 = 22x -65distributive property
28x -56 = 22x -65 additive property
6x = -9 subtractive property
x = -3/2 division
The first number in the ordered pair is the x-coordinate. If it is positive go that many units to the right of the origin(0,0) if it is negative go that many units left of the origin.
The second number is the y-coordinate. If it is positive go that many units up from the origin. If it is negative go that many units down from the origin.
For example: to graph the ordered pair of (3,4), I would go 3 units to the right and 4 units up.
An easy way to remember is to think of it as going to an elevator first you have to walk right or left to the elevator(x-coordinate) then the elevator goes up or down(y-coordinate).

ANSWER: (A) y= 10/3
EXPLANATION:
Create an equation for the graph⇩
From looking at the graph, the lemon juice in ounces is 3 times less than the water in ounces. Using this, we can create the following equation with y standing for the lemon juice and x standing for the water.
Y= x/3
Since we are solving for the amount of water, we have to substitute x for 10⇩
Y= 10/3
Enjoy your answer!⇩
y=10/3 (A)
