positive slope of 2, y- intercept of -7, x- intercept of 3.5
100
Explain when to use solid and dashed lines
dashed - with > OR <
solid - with > or = AND < or =
200
(0,0) and (-3, -3)
m = -1
200
Write in y = form
2x + 2y = -8
y = -4 - x
200
Find the slope and y-intercept
y = 3x -7
m = 3
b = -7
200
y = -5x
negative slope, y-intercept = 0, x-intercept = 0
200
Explain the steps to graph a linear inequality
1. determine solid or dashed line
2. determine m and b
3. graph the line.
4. Shade by substituting in a point.
TRUE statement - shade the side with that point
FALSE statement - shade the side without the point

(8, 8) and (8, 0)
m = undefined
300
Write the equation of the line with:
no y-intercept
slope is undefined
passes through the point (-4, 5)
x = -5
300
y = 7
Find the slope and y -intercept
m = 0
b = 7
300
y < 4|x| + 3
dashed V shape, slope of 4, Vertex at (0,3), shaded above
300
graph y< 4|x|
dashed V, slope = 4, y-intercept = 0, shaded on side with (1, 1)
400
(-3, -6) and (12, -6)
m = 0
400
Write teh equation in y = form
b= -2, m = 0
y = -2
OR y = 0x - 2
OR y = 0x + (-2)
400
Determine the slope:
a vertical line
undefined
400
2y -2x > -6
dashed line, slope = 1, y-intercept = -3, shaded on side with (0, 0)
400
How do you know where to shade the graph?
Solve for y first. If > or >=, shade above, if < or <=, shade below
500
(-2, -3) and (-2, -6)
undefined slope
