Which of the following is equivalent to the expression below?
(6x-4y+9) + (-3x - 2y)

(6x-4y+9) + (-3x - 2y)

6x - 4y + 9

(+) -3x - 2y + 0

3x - 6y + 9

Step-by-step explanation:

nb: I put the zero there to help solve it if there's no number at that place

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.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
