Solve this system of equations by graphing.
y = x – 3
Hint
First line has slope = 1 and y-intercept of -3, while the second has slope and y-intercept of 5.
Answer
The solution is (3, 0).
First line has slope and y-intercept of -2, while the second has slope and y-intercept of -2.
The solution is (0, -2).
First line has slope and y-intercept of -2, while the second has slope and y-intercept of 1.
The solution is (3, 2).
3x + y = -2
6x + 2y = 2
Both lines have slope = -3.
There is no solution, because the lines are parallel.
The first line has slope and y-intercept of 1, while the second has slope and y-intercept of 6.
The solution is (4, 3).
The first line has slope and y-intercept of -4, while the second has slope and y-intercept of -9.
The solution is (-5, -6).
x + y = -2
y = -5x – 10
The first line has slope = -1 and y-intercept = -2, while the second has slope = -5 and y-intercept = -10.
The solution is (-2, 0).
