(-4,-4)(1,3)
slope = (3 - (-4) / (1 - (-4)
slope = (3 + 4) / (1 + 4) = 7/5
y - y1 = m(x - x1)...using (-4,-4)
slope(m) = 7/5
y - (-4) = 7/5(x - (-4) =
y + 4 = 7/5(x + 4) <==here is one
y - y1 = m(x - x1)..using (1,3)
slope = 7/5
y - 3 = 7/5(x - 1) <== here is the other one

a- square root of b
Using a system of equations, it is found that Susan had 44 quarters, 11 dimes and 27 nickels.
--------------------------------
We are going to use:
- x as the number of quarters.
- y as the number of dimes.
- z as the number of nickels.
A <em>quarter </em>is worth $0.25. A <em>dime </em>is worth $0.1, and a <em>nickel </em>is worth $0.05. Total of $13.45, then:

4 times as many <u>quarters as dimes</u>, thus:

16 less <u>dimes than nickels</u>, thus:

Replacing in the first equation, we find x:





Now, with x, we find y and z:


Susan had 44 quarters, 11 dimes and 27 nickels.
