Answer: 60 ways.
Explanation: Suppose that we had 5 people, A, B, C, D, and E, and we had to select a P, VP, and S.
For the President, we have 5 different selections.
If we choose a president, then we can only pick 1 from 4 people for the VP.
Using the same logic, we'd have 3 different choices for the S.
Hence, we have 5 · 4 · 3 different ways.
Alternatively, this is:
different ways.

Answer:
3.) 63=3x+7y
4.) Y-intercept is 9
Step-by-step explanation:
(For 3) For every time a person gets a touchdown, x represents that
for every time a person person scored a successful extra-point attempt, y represents that.
And they team scores 63, so....
the equation would look like this
63=3x+7y
(For 4) You find the y-intercept by turning the standard form equatio into the slop intercept form
(Helper's note, multiplying by its reciprocal is the same as dividing it by a whole number, in the case dividing the number by 7 is the save as multiplying the number by )
Then plugging x=0 and solve for y, which in this case, y=9
(For the graphing) Turn 63=3x+7y into a slope intercept form, which is and graph from there
