Answer:
(-2, 0)
Step-by-step explanation:
y = 2x+4
6x - 3y = -12
Start by simplifying the second equation by dividing everything by 3 (this will make the math easier)...
2x - y = -4
Then, substitute 2x+4 for y into the second equation (this is because y = 2x+4)...
2x-3(2x+4)=-4
Distribute the -3
2x-3(2x)-3(4)=-4
2x-6x-12=-4
Combine like terms
-4x-12=-4
Add 12 to both sides
-4x-12+12=-4+12
-4x=8
Divide both sides by -4
x=-2
Plug -2 back in for x to solve for y:
y = 2(-2) + 4
y=-4+4
y=0
(x, y) = (-2, 0)
Answer:
Slope = 0
Step-by-step explanation:
Let's use the equation 
for this problem.
We have two points: (2,0) and (-2, 0)
Let's plug them both into the equation shown above.
Solve.
0 - 0 = 0
-2 - 2 = -4
= 
= 0
A zero in the numerator means this equation has a slope of 0.
Any line with a slope of 0 is a horizontal line.
Slope (rate of change) = 0
So the first one is 1 because 2+x=3
No need to look at the first two. It’s the third choice, the graph. Easily to tell if a graph is a function, draw lines down the x axis. A single line should not touch the line on the graph more than once. Also called the vertical line test. Therefore the answer is the graph. The first one is definitely wrong because all the x are the same. So if you were to draw a line down the x axis at 0, that line would touch all points there.
