Need help i have no idea what to do

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Neither

Line 2 and Line 3: Neither

Step-by-step explanation:

We will write all lines in slope intercept form i.e

where m is slope.

And check

a) If two lines are parallel they have same slope

b) If two lines are perpendicular they have opposite reciprocal slopes i.e

Equation for Line 1:

Already in slope-intercept form

Slope for Line 1 m is:

Equation for Line 2:

Converting into slope-intercept form:

Slope for Line 2 m is:

Equation for Line 3:

Converting into slope-intercept form:

Slope for Line 3 m is:

Now, finding answers

Line 1 and Line 2

Checking their slopes: ,

Both lines are perpendicular because they have opposite reciprocal slopes

Line 1 and Line 3

Checking their slopes: ,

Slopes are neither same, nor opposite reciprocal, so they are neither

Line 2 and Line 3

Checking their slopes: ,

Slopes are neither same, nor opposite reciprocal, so they are neither

The answers are:

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Neither

Line 2 and Line 3: Neither

it has the same slope and a different y-intercept

hope this : )
