The graph shows the tip amount that 14 different customers left, based on the their bill. A trend line has been drawn for the data. The equation for the line is: y = 0.14x + 2.5. Which BEST interprets the slope of the linear model? .

A) A $1 increase in the bill is associated with a $2.50 increase in tip amount.
B) A $2.50 increase in the bill is associated with a $1 increase in tip amount.
C) A $0.14 increase in the bill is associated with a $1 increase in tip amount.
D) A $1 increase in the bill is associated with a $0.14 increase in tip amount.

D)A $1 increase in the bill is associated with a $0.14 increase in tip amount.

Step-by-step explanation:

Slope is 0.14

= change in tip/change in bill

When change in bill is $1, change in tip is $0.14

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
