200
The coordinate point on any proportional graph that shows the Constant of Proportionality.
What is (1,k) or (1, CP)?
200
Is this equation proportional? Explain why or why not.
y= 4x + 10
Not proportional because the equation shows addition, the equation does not have a CP, and the equation does not show equivalent ratios.
200
Is this a graph of a proportional relationship? Explain why or why not.
No, because the graph does not start at the origin.
200
When one quantity is multiplied by a constant value to calculate a second quantity.
What is a proportional relationship?

Write an equation for this situation:
Elena jogged at a constant speed. She ran 3 laps in 5 minutes. Write an equation where d represents distance in laps and t represents time in minutes.
d = 0.6t or d = (3/5)t
t = 1.66d or t = (5/3)d
