Question 5

Domain

Answer 5

The set of input values for a function

Question 6

Range

Answer 6

The set of output values for a function

Question 7

Function Table

Answer 7

A table used to organize input, function rule, and output values

Question 8

Linear Function

Answer 8

A function in which the graph of the solution forms a straight line

Question 9

Answer 10

The change in the vertical distance (y-axis)

Question 11

Run

Answer 11

The change in the horizontal distance (x-axis)

Question 12

Direct Variation

Answer 12

When the ratio of two variable quantities is a constant (two quantities going the same direction)

Question 13

Constant of Variation

Answer 13

(K) The constant ratio in a direct variation
k=y/x
Y=kx

Question 14

Scatter Plot

Answer 14

A type of graph that plots data points to show a relationship between variables. Data points are ordered pairs.

Question 15

Line of Best Fit

Answer 15

The estimated linear equation y=mx+b that goes thru the middle of the data (approximately same number of points above and below the line)

Question 16

Correlation

Answer 16

The relationship (if any) between the x values and y values

Question 17

Direct Variation

Answer 17

When the ratio of two variable quantities is a constant (two quantities going the same direction)

Question 18

Slope-Intercept

Answer 18

An equation written in the form y=mx+b, where m is the slope and b is the y-intercept

Question 19
