-1.6r + 1.8

Step-by-step explanation:

-1.6 (r+2) +5

^ the -1.6 can be distributed to the (r+2) because it's basically multiplying

that becomes --> -1.6r + -3.2 + 5

Now the -3.2 and 5 are like terms so they can be solved together

-> -3.2 + 5 = 1.8

Now, -1.6r and 1.8 are not like terms because 1.8 does not have an r attached to it so you cannot do nothing from there

your answer becomes = -1.6r + 1.8

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.

answer: .64
