Answer:

a) $2.40

b) $16.80

c) y = -2.40x +16.80

Explanation:

a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4

Dylan spends $2.40 at lunch every day.

__

b. The y-intercept can be found from the formula ...

b = y1 -m(x1)

b = 12 -(-2.40)(2) = 16.80

Dylan's dad gives him $16.80 at the beginning of each week.

__

c. The slope-intercept equation is ...

y = mx + b

y = -2.40x +16.80
