The y-intercept is
A. the value of the independent variable when the dependent variable is zero; sometimes called the initial value.
B. the value of the dependent variable when the independent variable is greater than zero; sometimes called the initial value.
C. the value of the dependent variable when the independent variable is zero; sometimes called the zero value.
D. the value of the dependent variable when the independent variable is zero; sometimes called the initial value.

Is this relation linear? Explain why/why not.
YES
As x-values increase by 1, y-values increase by 3. x=3 is missing but the pattern remains consistent for x=4 and up.

Define the difference between discrete and continuous relationships. Give of an example of each.
A discrete function is a function with distinct and separate values. A continuous function, on the other hand, is a function that can take on any number within a certain interval. Discrete functions have scatter plots as graphs and continuous functions have lines or curves as graphs.

A gym charges a set membership fee, then a set cost per visit, as seen in the diagram.
a)What is the cost per visit(aka the slope)?
b)What is the membership fee(aka the initial value)?
c)What is the equation for this relation?
a) $2/visit; Slope = 2
b) Membership fee is $40 ; initial value/y-int = 40
c) y=2x + 40

A museum offers two types of memberships:
1)$6 per visit OR 2) a flat fee of $10 and 3$ per visit
Which type would be better for more than 3 visits? Explain
2 because for 4 visits it is cheaper($22 vs $24) and after that it increases by $3/visit vs $6/visit
