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
