The equation represents function a, and the graph represents function b:

function a: f(x) = x − 9

which equation best compares the slopes of the two functions?

a.) slope of function b = 2 x slope of function a
b.) slope of function a = slope of function b
c.) slope of function a = 2 x slope of function b
d.) slope of function b = − slope of function a

The correct option is A.

Step-by-step explanation:

The slope intercept form of a line is

              .... (1)

where, m is slope and b is y-intercept.

The equation of Function A is

     .... (2)

From (1) and (2) we get

It means slope of Function A is 1.

If a line passes through two points and , then slope of the line is

From the given graph it is clear that the line passes through two points (0,-1) and (1,1).

The slope of Function B is 2.

We can say that

Slope of Function B = 2 x Slope of Function A

Therefore the correct option is A.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
