I’m assuming the question is to find the equation of line.
Generally the equation of a line is in the form y=mx+c where m is the slope and c is the y-intercept. We know the slope is -9; so we have
y= -9x+c
Now substitute (6,7) in the equation to find c.
7=-9(6)+c
7=-54+c
c=7+54
c= 61
So equation of line is y = -9x+61
<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are given that the price of gas started at $2.25 and increased at a rate of 4% per year.
We are to write a function which models this situation using numerical values of A and r into the expression.
A = $2.25
r = 4%
Assuming x to be the time in years, the function would be:

Answer:
D, m<4 is 137°
Step-by-step explanation:
The answer would be D, because m<4 would be supplementary with the angle that's 43 degrees. Supplementary angles add up to 180, so this could be found through the following equation.
x + 43 = 180
x would represent <4
You would now subtract 43 from both sides.
x = 137
