Trivia
100
Describe a y-intercept.
The y intercept is the point where the line crosses the y axis. At this point x=0
100
Write a linear function with a slope of -9 and a y-intercept of 5
y =-9x+5
100
Does the table represent a linear or nonlinear function? Explain using the phrase "constant rate of change."
x y
2 9
4 18
6 27
8 36
This represents a linear equation because x and y have a constant rate of change.
100
Identify the slope of the linear equation
y = -x + 6
The slope is -1
100
What is the largest planet in our solar system?
Jupiter
200
Describe an x-intercept.
The x intercept is the point where the line crosses the x axis. At this point y = 0.
200
Write a linear function with a slope of -1 and a y-intercept of-2
y = -1x - 2
200
In the graph of x = 4, does this represent a linear or nonlinear function? Explain using the terms function, inputs and outputs.
This graph would represent neither linear or nonlinear because a vertical line is not considered a function as the input 4 is paired with multiple outputs.
200
What is the slope of a horizontal line?
The slope is 0.
200
True or false: All living things need water to survive.
True
300
The definition of slope is...
T steepness of a line.

300
Is the function represented by the ordered pairs linear or nonlinear? Explain.
(0,2) (3,14) (5,22) (9,38) (11,46)
This represents a linear function. Both x and y increase by a constant rate of change.

What is the formula of a line in Slope-Intercept Form?
400
What is the slope of the line passing through (0,2) and (-4,5).
3/4
400
Would the equation below produce a linear or nonlinear function? Explain using the phrase "slope-intercept form," and give the equation in slope-intercept form.
18x - 2y = 26
The equation would produce a linear function. It can be put into slope intercept form as y = 9x - 13.
