Question

Can someone please help me check my answers ?

Select the equation of the line that passes through the point (5, 7) and is perpendicular to the line x = 4.

y = 4
x = 5
y = 7
x = 7
My answer : C.

Which of the following lines is parallel to x = 7?

3y = 7
y = 7
x = y
x = 4
My answer : Not sure

Select the coordinates of two points on the line y = 8.

(8, 8) and (8, 0)
(8, −8) and (8, 8)
(0, 8) and (8, 0)
(0, 8) and (8, 8)
My answer : A

Answer 1

1) Yes

Answer 2

3) NO

Answer 3

Can you explain to me how to do 3 ?

Answer 4

y=7

Answer 5

oh gosh nvm read it wrong

Answer 6

`Select the coordinates of two points on the line y = 8.`

every point is of the form (x,y). The letter x comes first, then y follows.

every point on the line y = 8 has a y coordinate of 8. Some points include: (1,8), (3,8), (9,8), etc. The variable x can be anything you want. Just make sure y is 8.

Answer 7

and D

Answer 8

`Which of the following lines is parallel to x = 7?`

anything parallel to x = 7 is of the form x = k. The letter k is standing in for some fixed number.

Example: x = 92 is parallel to x = 7. Both are vertical lines that never cross each other.

Answer 9

okay thank you :)
