C because the two angles add to 180° making it supplementary
The answer is 133 dollars cuz 5580-3186 is 2394 and 2394 divided by 18 is 133
Hi There!
----------------------------------------------
Part A:
Slope Intercept Form: y = mx + b
m = slope (slope =
)
b = y intercept

b = 3
Answer: y = -1/2x + 3
----------------------------------------------
Part B:
Just substitue f(x) for y.
Function Notation = f(x) -1/2 + 3
----------------------------------------------
Part C:
This function given looks almost the same but the slope is different while the one stated in the question has a slope of +2 and the equation given at the start with the slope being -1/2.

Hope This Helps :)
K/5.4 + 99.4 = 13.1
k/5.4 = 13.1 - 99.4
k/5.4 = -86.3
k = -86.3 * 5.4
k = -466.02
