Answer:

Step-by-step explanation:
Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;
5 x 4 = 20
If a color is selected at random the probability would be

our part is 5
our whole is 20
so the probability would be;
or
when reduced

Slope can be found but putting the equation in slope intercept form (y=mx+b)
6y=3x-12
y= 0.5x-2
M is your slope, b is the y intercept.
So the slope is 1/2, yintercept is (0,-2)

Distribute -3 in
-3x + 42 + 6x
3x + 42
