Hope this helps! Comment any questions <3

20/21

Step-by-step explanation:

2/21 + 6/7

Get a common denominator of 21

2/21  + 6/7 *3/3

2/21 + 18/21

20/21

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.
