Which intercept stays the same? Which changes? Change of slope - faster, slower, same?
x-intercept changes
y-intercept stays the same
slope is at a faster rate
200
Identify whether the function is linear or non-linear, explain why. 
Non-linear because there is not a constant rate of change.

Which intercept stays the same? Which changes? Change of slope - faster, slower, same?
x-intercept changes
y-intercept stays the same
slope has a slower rate
