Craig likes to collect records. Last year he had 10 records in his collection. Now he has 14 records. What is the percent increase of his ​collection?

20%  

Step-by-step explanation:

We can solve this with the rule of three.

If 100% represents 10 records, what percentage would be for 12 records?

So, if we subtract , it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.

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.
