y = x + 4
y = 2x + 5
r + s = -6
r - s = -10
x = 4y
2x + 3y = 22
Does y > 3x - 1 have 1) dotted or solid line, and 2) shade above or below the line?
What are dotted and above?
y = 3x - 2
y = -x - 2
8a + 5b = 9
2a - 5b = -4
y = x - 2
3x - y = 16
Graph y <= 4x + 1
.
y = -3
x = 5
2x + 3y = 6
3x + 5y = 15
y = 3x - 1
7x + 2y = 37
Where the solution regions to each inequality overlap.
What is the solution to a system of inequalities?
y = (1/3)x - 3
2x - y = 8
2a - 4b = 12
-8a + 16b = -48
3s - 2t = 4
t = 2s - 1
Graph the system:
y < -x + 1
y > x - 1
.
y - 3x = 3
y = 3x - 2
(1/3)x + (1/4)y = 10
(1/3)x - (1/2)y = 4
t + u = 12
t = (1/3)u
The number of solutions to the system:
2y + x > 1
4y < -2x - 3
What is no solutions?
