Answer 2

find you slope first then take the opposite sign and the reciprocal of the number

Answer 3

What is the anwser?

Answer 4

so what is the slope?

Answer 5

gotta go, maybe someone will help you

Answer 6

Ok, so you need to solve for y, then do as precal said and take the opposite reciprocal
meaning negative flipped fraction

Answer 7

so you got?

Answer 8

nope!

Answer 9

take your equation and solve for y
tell me what equation you get at that point
hint: y=?

Answer 10

No idea! I am So stupid!

Answer 11

Sorry, once we get down to pre-algebra stuff I forget how to teach it. :/

Best I can say is whatever you do to one side you have to do it to the other side.

Answer 12

Write the slope-intercept equation of the line perpendicular to y = 5/2 x - 2, which passes though the point (0, 2).
Answer

y = 5x + 2

y = -2/5x + 2

y = 2x + 5

y = 1/2x + 5

Answer 13

the number in front of x is (-1/3)
you want +3

Answer 14

sorry gotta go

Answer 15

First change it into Slope-Intercept form.
y = mx + b
where m is slope.

x + 3y = 5
Subtract x.
3y = -x + 5
Divide by 3.
y = -1/3 + 5/3
So your slope is -1/3.

However it asks for the slope of the line perpendicular to this one.

Slope of perpendicular lines are the opposite reciprocal - change the value from positive to negative or vice versa, then find the reciprocal. ex. opposite reciprocal of -1/2 is +2/1 or 2

Answer 16

So what is the opposite reciprocal of -3/1?

Answer 17

1/3!

Answer 18

Sorry I meant to say, what is the opposite reciprocal of -1/3. My mistake!

Answer 19

So what is the opposite reciprocal of -1/3?

Answer 20

I believe I stated it already +3

Answer 21

ohh sorry! Didn't see it. (:
