100
Is this a function?
Yes it is a function!
100
Is this graph linear or non-linear?
Non-linear the line is not straight!
100
What is the equation in slope-intercept form?
m = -2 (7, -4)
y = -2x + 10
100
What is the equation for the graph?
The answer is: y = 2/3x -4
200
Which graph shows a function?
Graph 1. shows a function!
200
Is this table linear our non-linear?
Non-linear, there is no constant rate of change!
200
What is the equation in slope-intercept form?
m = 4; ( -2, 1)
The answer is: y = 4x + 9
200
Between 8 am and 12 am is the graph decreasing or increasing?

300
Does this map represent a function?
Not a function, there are two outputs for one input!
300
Is this equation linear or non-linear?
y = 6x + 8
Yes this equation is linear because its in y=mx+b form!
300
What is the equation in slope-intercept form?
(3, -10) and (10, -38)
The answer is: y = -4x + 2
300
What does the slope mean in the context of this situation?
The slope is 15 meaning that for each hour they gain $15!
