Question

Is the answer: 43/4?
Find the slope intercept form of the equation of the line through the point (0,9) perpendicular to the graph of y=2x+1 1/3 (keep in fraction form)

Answer 1

The Slope-Intercept Form is an equation. The correct response cannot possibly be "44/3".

Answer 2

could you type the question again ?

Answer 3

My nephew brought this over tonight for help. Neither me or my husband can remember how to do this.

Answer 4

what is the equation of line given ? is it

Answer 5

it is unclear whether you typed

Answer 6

No, it's y=2X+1and 1 third

Answer 7

Find the slope-intercept form of the line through the point (0,9), perpendicular to the graph of y=2X+1and one third

Answer 8

Slope-Intercept Form looks like this: y = mx + b

You need a slope, m, and an intercept, b, in order to solve the problem.

The slope is ALMOST given. It's only a hint.

Perpendicular to y = 2x + something. This slope is 2. A perpendicular slope needs to be -1/2 so that (-1/2)*2 = -1. That -2 is a little bit magic.

Okay, now we know the new line lies like this: y = (-1/2)x + b

You need to follow this far before the last piece.

Answer 9

1 and 1/3 = 4/3 , that should be easy to do based on what tk***y as suggested

Answer 10

Yes, but I have been out of school for 20+ years, lol!

Answer 11

* That "-1" is a little bit magic. Sorry about that typo.

Answer 12

y=2x+4/3, slope of this line is say m = 2
lets says slope of line perpendicular to it is say k
if lines are perpendicular ,product of slopes is = -1

i.e. m*k=-1
so slope of line perpendicular to it is k=-1/2

Answer 13

lets say equn of line that is perpendicular is y=kx+C we know its slope k = -1/2 and it passes via (0,9)

Answer 14

9=0+c
so, c=9
eqn of this line is y=-1/2 * x +9

Answer 15

or y=-0.5x+9

Answer 16

but since you want it in fraction form you will leave it as
Y= (-1/2)X+9

Answer 17

Oh thank you, thank you!

Answer 18

I have given the method, but verify the answer, typing fast , may have made some errors but the METHOD is what matters

Answer 19

(0,9) so what are these numbers?

Answer 20

(0,9) IS THE POINT THROUGH which the perpendicular line PASSES

Answer 21

CAPS have been used to highlight the points, no offense intended

Answer 22

They are directions for finding your way around a 2-dimensional coordiante system. Typically, the x value is lined up on a horizontal axis (positive to the right) and the y values is lined up on a vertical axis (positive going up). (0,9) means 0 in the x direction and 9 in the positive y direction.

Answer 23

But do I remember correctly labeling the top of those numbers with alphabet letters? You know, in order to use them?

Answer 24

So it's x and y

Answer 25

That's it. (x,y)

Answer 26

It's slowly coming back to me. Thank you for your help!

Answer 27

Think about it as you go to sleep. It will feel better in the morning.

Okay, stop laughing!!

Answer 28

Ugh, his assignment isn't due until Friday so we can look at his other problem tomorrow.

Answer 29

There you have it, then. Time to dream of coordinate axes!!

Answer 30

I paid my dues in high school and college! I'm dreaming of shopping these days!

Answer 31

(sigh) Gone over to the dark side, you have!

Answer 32

Thank you for putting up with me!
