Question:
Linear equations
1. Complete the ordered pair so it is a solution to the given linear equation. give the answer as an ordered pair using parentheses and a comma.
3x + y = -7 (,2
2. solve these 2 system of equations
x - y = -5
x + 4y = 15
5x + y = 0
-5x + y = -10
3. Find the slope, if possible of the line passing through the pair of points (1,9) and (2,6).
