Answer:
y-intercept is 30
Step-by-step explanation:
Given the model
comparing this model to the equation of a straight lines we can get the y- intercept

The y- intercept is 30 which is the constant factor and it describes to us about the one-time registration fee of $30.
The slope is -2/3 I hope this helped
Well, if every box is a unit, it would be 6 units in length.
