What is the input (x or y)?
What is the output (x or y)?
Input: X
Output: Y
100
The letter that stands for rate of change/slope in a linear equation form.
M
100
Find the solution to: -2x - 13 = 7.
-10
100
This is what the 'b' represents in y = mx + b.
Y-intercept/initial value
100
Give the next three terms in this sequence:
-9, -3, 3, 9
Is this sequence arithmetic or geometric?
15, 21, 27
Arithmetic
200
The rise over the run.
Rate of change or slope
200
Which of the following has a larger slope?
y=4+2x
or
Equation has a slope of 2.
The table has a slope of 3.
200
What is the test I can use to see if a graph is a function?
Vertical line test
200
What is the rate of change in y = 2/5 x - 9
2/5
200
Is this sequence geometric or arithmetic?
-1, 3, -9, 27
Write the RECURSIVE formula.
an=an-1(-3)
a1=-1
300
This is the point where the graph crosses the y-axis.
The y-intercept or initial value
300
Stan's speed steadily increases as he walks from home to school. Sketch a graph with labelled axes to show his distance from home with respect to time.
Graph should have both axes labelled and how a line with a slope that increases (not linear)
300
What is the difference between an explicit and recursive formula?
Explicit formulas can find any term in the sequence; recursive formulas can only find terms when you know the previous term.
300
What is the initial value in y = -3x - 1?
-1
300
Why might you prefer to know the explicit formula of a sequence instead of the recursive one?
The explicit one will allow you to determine any term in the sequence.
400
Define function. State how it differs from a step function.
A relation for which each input has exactly one unique output.
Step functions are not continuous, but discrete.
400
Write the equation of this graph.
If image does not show--> sketch the graph of the inequality 5y+3x>15
If image shows: y is greater than or equal to -1/2x-4
400
What is the difference between geometric and arithmetic sequences?
Geometric sequences have a common ratio (multiplying or dividing by the same number)
Arithmetic sequences have a common difference (adding or subtracting the same number)
400
Define linear function.
A function that has a constant rate of change and makes a straight line when graphed
400
Write the explicit formula for this sequence and then find the 7th term.
-5, -10, -20
an=-5(2n-1)
a7=-5(26)=-320
500
What are the three forms of linear functions? Provide their formula
Slope intercept
Standard Form
Point Slope
500
Sketch the graph for this function:
y=-2x+4
correct graph
500
Rewrite this literal equation for B:
Ax+By=C
(C-Ax)/y=B
500
Sketch the graph of the inequality, then decide whether (2, 1) is a part of the solution set.
y>3x+1
- Correct graph
- Dotted line
- Shade above
- NOT a part of the solution set
500

2, 4, 8, 16, 32, 64, 128
an=2*2n-1
256, 512, 1024
