Answer:


Step-by-step explanation:Write as two points in terms of: (number of people, cost in $)

�

(15,120) and (25,200)

�

Find the equation of the line using:

�

m = (y2 – y1) / (x2 – x1) and y = mx + b

�

Equation:

�

Y = 8x

�

plug in x = 40

�

y = 8(40) = 320

�

A party of 40 people will cost $320.00.

�

Slope:

�

m = 8 $/person

�

For every person that attends the party, the caterer’s bill increases by $120.00.

�

y-intercept: 0

�

(0,0)

�

This tells us that if no one attends the party, the caterer’s bill will be $0.00. So the

�

caterer has no base cost they charge to caterer a party.
