-2x + 4y = -4
x - 3y = 6

(-6, -4)

Step-by-step explanation:

Let's eliminate x using the addition / subtraction method:

-2x + 4y = -4

  x - 3y = 6  

becomes

-2x + 4y = -4

2x - 6y = 12

-2y = 8

Dividing both sides by -2, we get y = -4.  

Substituting -4 into the 2nd original equation results in:

x - 3(-4) = 6, or x + 12 = 6, or x = -6

The solution of this system of linear equations is therefore (-6, -4).

1. 34

2. 268

3. x=14.4

step-by-step explanation:

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.
