2x -¬ y = 6
2x + y = 10
line 1 2x -¬ y = 6
- ¬2x + y = ¬10
line 2 0 = ¬4
line 3 0 ≠-4 so there is no solution
line 1
line 2
line 3
there is no error
which of the following situations would give you a system of equations that have at least 2 solutions?
two lines are parallel and have different y¬-intercepts.
two lines have the same slope and both pass through the origin.
two lines are perpendicular and have the same y-intercept.
two lines have negative slopes and different y¬-intercepts.
solve the system of equations.
3x = ¬-31 + 2y
5x + 6y = 23
x = ¬-5, y = 8
x = ¬- 29, y = ¬- 28
no solution
infinite solutions
solve the system of equations.
6d + 3f = 12
