100
Are the lines parallel, perpendicular or Neither?
y = 9x - 6 and y = 6x - 9
What is neither?
The slopes are neither the same (parallel) or opposite reciprocals (perpendicular)
100
Factor the quadratic into 2 linear binomials.
x2 + 5x + 6
What is (x + 2)(x + 3)
100
Solve the inequality
2x - 10 > 6
What is x > 8
100
4x + 5 = 13
What is x = 2?
100
What is the slope of the line produced by the relationship:
What is –3? or -3/1
Remember: Slope (m) is the change in y divided by the change in x
200
Are the lines parallel, perpendicular or neither?
y = 1/2x - 6 y = 5 + 3/6x
What is parallel?
The slopes are the same when they are both reduced to lowest form.
200
Factor the quadratic into to linear binomials.
x2 - 9x + 8
What is (x -1)(x - 8)
200
Solve the inequality
6(x - 2) < -36
What is x < -4?
200
2(6x + 11) = 130
What is x = 9?
200
Find the y-intercept.
What is (0,5)?
300
Are the lines parallel, perpendicular or neither?
y = 8 x = 4
What is perpendicular?
y = lines are horizontal
x = lines are vertical
300
Factor the following quadratic into two linear binomials.
x2 - 3x - 10
What is (x - 5)(x + 2)
300
Solve the inequality.
-2x - 9 < 17
What is x > -13?
Don't forget, the inequality sign flips when you divide or multiply by a negative number.
300
5+ 2(3x + 4) - 2x = 1
What is x = -3?
300
Write an equation for the table.
What is y=3x - 1?
Remember, the y-intercept is (0,b) and the slope (m) is change in y divided by the change in x
400
Are the lines parallel, perpendicular or neither?
y= 2x - 1 6x - 3y = 12
What is parallel?
When you convert the standard equation to slope intercept, the slopes are the same.
400

What is shade BELOW a DOTTED line?
400
4a + 2a + 3 = 15
What is a = 2?
400
Write a linear function relationship.
y=2/5x-1
Remember, slope is rise/run
500
Are the lines parallel, perpendicular or neither?
y = 3x - 2 y = -1/3x + 9
What is perpendicular?
The slopes are opposite reciprocals.
