Question

Given the system y = 2x + 2 and y = 2 x, which statement below is true?

1. There are no solutions

2. The system has exactly one solution.

3. (3, 8) is a solution of the system


4. (8, 3) is a solution of the system.

can you help me !!!!! PLEASE

Answer 1

y= 2x+2

y= 2x

Let's solve y=2x+2 for y

We gonna substitute 2x+2 for y in y=2x

y=2x

2x+2 =2x

Now add -2x to both sides

2x+2-2x=2x-2x

2=0

Add -2 to both sides

2-2 = 0-2

0 = -2

There are no solutions

Answer : A

I hope that's help:)

Answer 2

-- The graphs of the lines have the same slope and different y-intercepts.

-- The graphs of the lines are parallel, and 2 units apart.

-- The lines don't intersect anywhere.
That's another way of saying there's no point that's on both lines.
That's another way of saying that the system of equations has no solution.
