Question

Parallel and Perpendicular Lines:

1. Write the equation of the line which passes through (5, –2) and is parallel to x = 4.

2. Write the equation of the line which passes through (2, 1) and is perpendicular to x = –2.

3. Write the equation of the line which passes through (–4, 2) and is parallel to y = –x + 6 in slope-intercept form.

4. Write the equation of the line which passes through (2, –3) and is perpendicular to y = 4x + 7 in standard form.

5. Using complete sentences, describe one example of a place in your everyday life of parallel lines and one example of perpendicular lines. You may also provide a digital image or self-created picture. (2 Examples)

Answer 1

Thanks for helping me out! (:

Answer 2

yuck 5 questions...

Answer 3

:/ I am totally confused. I tried to do this assignment like 6 times already and failed each time. :(

Answer 4

if its parallel to x=4
gradient is 4
use formula https://upload.wikimedia.org/math/4/a/b/4ab74ac53655875c5ea0b749148610ab.png

Answer 5

y+2 = 4(x-5)
y+2 = 4x - 20
you can make it look better if you wish

Answer 6

ill only do question 1 for you :)

Answer 7

I'm following you.

Answer 8

do you understand it?

Answer 9

so thats basicly question 1 done.

Answer 10

So the answer is: y+2 = 4x - 20
??

Answer 11

Fine ill do 1 more
2. Write the equation of the line which passes through (2, 1) and is perpendicular to x = –2
since its perpendicular
m1 = -1/m2

Answer 12

yea thats the answer (you can make it nicer if you want)

Answer 13

Thank you so much.

Answer 14

Also after question 2 could you help me with the last one and I'll do the rest. . .

Answer 15

gradient = 1/2
using formula

y-1 = 1/2(x-2)
2y - 2 = x-2
2y-x=0

Answer 16

well perpedicular lines can be seen
-When a pole makes 90 degrees with the floor.
-The corners of a piece of paper
-The edge of a step
You can choose one :) but make the sentence more complicated :)

Answer 17

parallel lines can be found in
-train tracks when they are going in a straight line
- a very very long ruler
-The sides of a straight road
Choose one if you wish but make sentence more complicated :)

Answer 18

Thank you so much! (:
