Question

I always get these wrong Help

Answer 1

Answer:

1. A possible answer is:

• y = x + 1
• y = x - 3

Another possible answer

• y = 3x + 2
• y = 3x - 8

Another possible answer

• y = 2x + 1
• y = 2x - 7

2. There is no solution because the the lines are parallel to each others but are located at different y-intercept.

Step-by-step explanation:

1. The lines are parallel to each others which means they must have the same slope.

So you can choose the value for any slope you want.

The lines are increasing so the slope has to be positive. I just chose my slope to be m=1; it can be any positive numbers.

I will be using the slope intercept formula to plug in my values:

    y = mx + b

Where m is the slope and b is the y-intercept value.

The first line is above the x-axis so it must have a positive b value for the y-intercept. I let the value be b=1 giving me:

• y = x + 1

The second line is below the x-axis alot more than the first line, so the y-intercept must be negative. I just pick a random negative value and it was b=-3 giving me:

• y = x - 3

2.

The lines are parallel to each other, which means they will never touch each other. A solution to a system of equation can only exist if the line touch each other. Parallel lines that are separated at different points will never touch each other therefore there is no solution.

Answer 2

Facts honestly agree a lot more than i thought
