2) Find the length of the segment indicated. Round your answer to the nearest tenth if necessary. A) 15
B) 9.4
C)16.7
D) 7.3

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
