\(m = \frac{y_2-y_1}{x_2-x_1}=\frac{3-2}{4-3}=1\)
Parallel lines have the same slope and only choice \(D (y=x)\) has slope of 1.
Five years ago, Amy was three times as old as Mike. Mike is 10 years now. Therefore, 5 years ago Mike was 5 years.
Five years ago, Amy was: \( A=3×5=15 \)
Now Amy is 20 years old: \(15 + 5 = 20\)
