False
If the domain involves time, is the domain discrete or continuous?
Continuous
What does the m stand for in y = mx +b?
Slope
What kind of rate of change does the graph of a linear function show?
Constant Rate of Change
What kind of line do we graph for a continuous function?
Full, straight line
What does the b stand for in y = mx + b?
y-intercept
Do these coordinates represent a linear or nonlinear equation? (1,1), (2,3), (3,5), (4,7)
Linear Function
What kind of line do we graph for a discrete function?

Is the following a linear function? Why or why not?
y = 2x + 1
Yes it is linear. It is in slope intercept form.
