Answer:
C
Step-by-step explanation:
The first one (0,7) tells you that when x isn't there, the amount of money is 7.
That means that the y intercept is 7.
When x = 1 the total is 15
Money saved = ax + 7
15 = a*1 + 7 Subtract 7
15-7 = a + 7-7
a = 8
The equation is f(x) = 8x + 7

The difference between the prediction & the reality is 122-57 =65 votes.
Then over 122, the error was 65 votes &
the error ratio is 65/122 = 0.5327 ==>53.27% Or 53.3% (rounded)
hi this is my first answer
a straight angle has 180°,
here your given angle is 60+60=120°
so your missing angle is 180-120=60°
