Is the point (3, 2) a solution to the equation
y = -(3/4)x + 3? Explain your answer based on the graph drawn.
No, because 2 = -(3/4)*3 + 3 is False; or

In attempting to solve the system of equations
y = 3x - 2 and 6x - 2y = 4, John graphed the two equations on his graphing calculator. Because he saw only one line, John wrote that the answer to the system is the empty set. Is he correct? Explain your answer.
No, because the two equations are the SAME line, thus
there are infinite solutions and NOT an empty set of no solutions.

Byron has 72 coins in his piggy bank. The piggy
bank contains only dimes and quarters. If he has
$14.70 in his piggy bank, which equation can be
used to determine q, the number of quarters he has?
1) 14.70 + 0.25q = 72
2) 0.10(q - 72) + 0.25q = 14.70
3) 0.10(72 - q) + 0.25q = 14.70
4) 0.10q + 0.25(72 - q) = 14.70
