Question

What lines are parallel?

Answer 1

Given ↓

• The following equations → y=3x-2, y=1/3x-3, y=x,  y=3, y=0 and y=3.

To Find ↓

• Which two lines are parallel?

Calculations ↓

In order to find out which two lines are parallel, let's find the slope of each line first.

The slope of the line y=3x-2 is 3.

The slope of the line y=1/3x-3 is 1/3

The slope of the line y=x is 1

The slope of the line y=3 is 0

The slope of the line y=0 is 0

Now, if two lines have the same slope, they are parallel to each other.

So if a line's slope is 0, the line parallel to it has a slope of 0.

So the parallel lines here are ↓

y=0 and y=3

Answer 2

Answer:

C

Step-by-step explanation:

y=0 gives the straight horizontal line passing through (0,0)

y=3 also gives straight horizontal line passing through (0,3)
