Emily is entering a bicycle race for charity. Her mother pledges $0.20 for every 0.25 mile she bikes. If Emily bikes 8 miles, how much will her mother donate?

$6.40

Step-by-step explanation:

0.25/0.20=0.80

0.80*8=6.40

or 0.20*8=2

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.
