    1. Write an equation of the line that passes through (0, -4) and is parallel y = (3/4)x + 2. Write the answer in slope-intercept form.

    2. Solve the system of equations by substitution:

    x + 2y = 9
    3x - y = 13

    3. Solve the system of equations by substitution:

    4x - 3y = 1
    12x - 9y = 3
