Find the slope, m = (change in y) / (change in x)
0-(-2)
Here, m = ------------- = 1/4
8 - 0
y-k = m(x-h) becomes y+2 = (1/4)(x), or y = (1/4)x - 2
Then the desired equation is y = (1/4)x - 2 (slope-intercept form)
Answer:
Step-by-step explanation:
y = mx + b
we can see the slope is down hill, so it's negative
when the X is zero then it's 2
b = 2
slope is rise over run 2/3
y = -2/3x + 2
the slope is -2/3 (note the negative)
the y intercept is 2

Determine the percentage of the shaded cubes
First, we calculate the number of boxes:
Express as multiplication
This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:
<em>30% were shaded</em>
The first choice can be any one of the 8 side dishes.
For each of these . . .
The 2nd choice can be any one of the remaining 7.
Total number of ways to pick 2 out of 8 = (8 x 7) = 56 ways .
BUT ...
That doesn't mean you can get 56 different sets of 2 side dishes.
For each different pair, there are 2 ways to choose them . . .
(first A then B), and (first B then A). Either way, you wind up with (A and B).
So yes, there are 56 different 'WAYS' to choose 2 out of 8.
But there are only 28 different possible results, and 2 'ways'
to get each result.
