Now he has as many cards as Billy who owns 2 packs and 20 loose
cards. If all the packs had the same number of cards, how many
cards are in each pack?

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

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.
