Question

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).
Choose one answer.
a. y = 2x + 6
b. y = −one halfx + 3
c. y = −one halfx + 6
d. y = 2x + 3

Answer 1

So can you work out?

Answer 2

yeah

Answer 3

So this is similar to the parallel problem except the rule for perpendicular lines is that the gradient/slopes are inverse of each other so if you had a slope of -3 the perpendicular line would have a slope of 3.

Answer 4

Remember that this is not parallel. It's perpendicular to the line y = 2x+2.

Answer 5

So the slope for the other line is -2?

Answer 6

No

Answer 7

or -1/2

Answer 8

Yeah correct!

Answer 9

So it is b or c?

Answer 10

now i plug in the x?

Answer 11

As previously check whether the y value is 3 by plugging x = 6.

Answer 12

c?

Answer 13

Can you show the calculation steps?

Answer 14

y= -1/2+6

Answer 15

-1/2x

Answer 16

so 6 x -1/1 = 3

Answer 17

wait.

Answer 18

oh ok so
y= -1/2x + 6
-1/2 x 6 = -3
-3 + 6 = 3
y=3

Answer 19

here did you get the 6 from?

Answer 20

the x ?

Answer 21

I have to recheck too. :D

Answer 22

youre math is a bit off. it should be b double check yotur work

Answer 23

Im not sure where i went wrong ;/

Answer 24

@Rhystic How can it be b?

Answer 25

Kyle is right unless I am wrong.

Answer 26

should i open up another thread and do another?

Answer 27

Your wish. :)

Answer 28

You can check these by plotting them online.

Answer 29

no youre right my math was off sorry about that.
