Starts With S
y = x + 4
y = 2x + 5
r + s = -6
r - s = -10
Two lines that cross.
One
y = 3x - 2
y = -x - 2
8a + 5b = 9
2a - 5b = -4
Two lines that have the same slope.
y = -3
x = 5
2x + 3y = 6
3x + 5y = 15
The number of solutions in this set
4x + 8y = 20
−4x + 2y = −30
What is one?
y = (1/3)x - 3
2x - y = 8
2a - 4b = 12
-8a + 16b = -48
Two lines that have the same slope and same intercept.
When you have x=8, what can you do to find the y value?
What is substitution
y - 3x = 3
y = 3x - 2
(1/3)x + (1/4)y = 10
(1/3)x - (1/2)y = 4
The number of solutions in this set:
5x - 4y = 6
-5x = -4y - 2
