It costs $8 for 20 packages of skittles. what is the unit rate?

we know that

$8 = 20 packages

$1 = x

Let x be the unit rate

x= 20/8

x = 2.5

I hope that's help !

question is incomplete.

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.
