Number of lunches: 0 5 10 15
Total amount of lunch money left ($): 100 75 50 25
Which equation, in standard form, represents the relationship between the number of lunches, x, and the amount of lunch money Aaron will have left, y?

A. x + 100y = 5
B. x + 5y = 100
C. 5x + y = 100
D. 100x + y = 5

(5,100) (10,75)
first find the slope
75-100=-25
10-5=5
-25/5= a slope of -5
the y-intercept is 100 because that is when x is zero
y=-5x+100
then add 5x to each side
5x+y=100 is your final answer.
I find it easier to start in y=mx+b form and go from there. Hope this helped!!

Answer:

C, 5x + y = 100
