First, let's convert each line to slope-intercept form to better see the slopes.

Isolate the y variable for each equation.

2x + 6y = -12

Subtract 2x from both sides.

6y = -12 - 2x

Divide both sides by 6.

y = -2 - 1/3x

Rearrange.

y = -1/3x - 2


Line b:

2y = 3x - 10

Divide both sides by 2.

y = 1.5x - 5


Line c:

3x - 2y = -4

Add 2y to both sides.

3x = -4 + 2y

Add 4 to both sides.

2y = 3x + 4

Divide both sides by 2.

y = 1.5x + 2


Now, let's compare our new equations:

Line a: y = -1/3x - 2

Line b: y = 1.5x - 5

Line c: y = 1.5x + 2

Now, the rule for parallel and perpendicular lines is as follows:

For two lines to be parallel, they must have equal slopes.

For two lines to be perpendicular, one must have the negative reciprocal of the other.

In this case, line b and c are parallel, and they have the same slope, but different y-intercepts.

However, none of the lines are perpendicular, as -1/3x is not the negative reciprocal of 1.5x, or 3/2x.

<h3><u>B and C are parallel, no perpendicular lines.</u></h3>

Use the perimeter to find the length of segment AD. This is the distance from A to D. Explain how you found your answer. Please
jekas [21]

Answer:

AD = 5 units

Step-by-step explanation:

Given:

Perimeter = 18 units

BC = 4 units

CD = 3 units

Required:

Length of segment AD

Solution:

Perimeter = AB + BC + CD + AD

We can easily find AB,

AB = 6 units (distance from A to B)

Plug in the values

18 = 6 + 4 + 3 + AD

18 = 13 + AD

Subtract 13 from each side

18 - 13 = 13 + AD - 13

5 = AD

AD = 5 units
