Identify the like terms in this expression: 3xy + 2x – 7xy + 4x2 a. 3xy and –7xy b. there are no like terms in this expression. c. 3xy, 7xy, and 2x d. 2x and 4x2

I believe the answer is C!

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.
