Answer:

Step-by-step explanation:

Graphing:
Slope intercept form y=mx+b
a is y, p is x
y=-2x+14
y=-x+9
Intercept at (5,4)
The number generator is fair. it picked the approximate percentage of red most of the time.
16-18=-2
You can use a number line to help you.
(8x-2)/9=2
times both sides by 9
8x-2=18
add 2 to both sides
8x=20
divide both sides by 8
x=5/2
B is answer
