Margie is planning a dinner banquet. The equation
C=750+42g models the relation between the cost in dollars,
C, of the banquet and the number of guests,
g. Interpret the slope of the equation.

the x is the independent variable so the guests the y is the dependent variable so the cost.

Step-by-step explanation:

because so when there are 100 people there is 4,200 +750 and the cost is 4,950

The slope, 42, means that for each additional guest the cost of the banquet increases by 42 dollars.

Step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
