3x-5+6y-9+10x What are the variables?
How many terms?
What are the coefficients?
What are the constants?
What are the like terms?

13x+6y-14

Step-by-step explanation:

a variable is a symbol in this case (x) represents a number

term-any number

5 terms

the coefficient is used to multiply the variable. Or the number next to y and x

constants are numbers alone, for example -9 and -5

like terms are the ones that have the same variables and paterns.

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.
