100

Find the output in y=x+7 if x=2

y= 2+7 so y=9

100

The slope of the line between the points (2,5) and (7,9)

What is 4/5

100

Identify the domain

(-1,4) (3,6) (7,8) (11,10)

{-1, 3, 7, 11}

100

In the function y=3x+1, what is the rule?

multiply by 3  then add 1

100

Define slope

change in the y-values over change in x-values or rise over run

200

Find the output in the function y= x/4 + 2, when x=16

y= 16/4 + 2 so y= 4+2 = 6

200

Slope between (19,3) and (15,3)

What is 0 or 0/-4

200

Identify the range

(-1,3) (3,7) (7,11) (11,15)

{3, 7, 11, 15}

200

In the function y=-2x+4, what is the rule?

Multiply by -2 then add 4

200

What is the definition of range?

The set of output values (all values of y).

300

In the function y=-3x-10 find the output when x=-1

y=-3(-1)-10;  y=-7

300

Slope of a line between (4,7) and (-2,5)

What is 1/3 or 2/6

300

Find the missing domain value (find the pattern)

(2,5) (6,3) (10,1) ( ? ,-1) (18,-3)

What is 14, pattern is add 4

300

What is the rule in y= x/5 - 2

divide by 5 then subtract 2

300

What is the test to tell if a graph is a function?

Vertical Line Test (VLT)

400

Find the output in the function y=x/-2 - 3, when x=10

y= 10/-2 - 3; y= -5 - 3 so y=-8

400

Slope of a line between (19,-16) and (-7,-15)

What is -1/26

400

(-2,11) (0,8) (2,5) (4, ? ) (6,-1)

What is 2, pattern is subtract 3

400

What is the rule in the function y=-3x-10

multiply by -3 then subtract 10

400

What is the definition of domain?

The set of all input values or the x-values

500

In the function y= 2x/3 +1 find the output if x = 6

y= 2(6)/3 + 1; y= 12/3 + 1 so y= 4+1 = 5

y=5

500

Slope of a line between the points (-3,10) and (-3,4)

What is undefined

500
