    1. Find the slope of the line that passes through the points (2, 3) and (5, 8).

    2. Find the equation of the line that passes through the points (3, -2) and (4, -2).

    3. Find the equation, in standard form, with all integer coefficients, of the line perpendicular to x + 3y = 6 and passing through (-3, 5).

    4. Solve the system of equations using the substitution method.
    If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is "no solution" or "infinitely many solutions."
    -3x + y = 1
    5x + 2y = -4

    5. Solve the system of equations using the addition (elimination) method.
    If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is "no solution" or "infinitely many solutions."
    -7x + y = 8
    2x - y = 2

    6. Solve the system of equations using the addition (elimination) method.
    If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is "no solution" or "infinitely many solutions."
    3x - 2y = -7
    -9x + 6y = 21
