Question

Find the slope, if it exists.
3x-4y=8 help ?

Answer 1

y=mx+b Slope = m. Does this help?

Answer 2

yes

Answer 3

So redo the equation and solve for y and you will have your slope.

Answer 4

3/1 ?

Answer 5

nope thats wrong

Answer 6

No..but close. If you rewrite the equation you get 4y=3x-8 Do you see this?

Answer 7

yes

Answer 8

do you add 8 on both sides ?

Answer 9

I subtracted eight from both sides and added 4y to both sides. We are trying to isolate the y value to one side of the equation

Answer 10

whats next

Answer 11

4y=3x-8...Now show as y=

Answer 12

subtract 4y from both sides ?

Answer 13

No

Answer 14

What do you do to 4y to make it y

Answer 15

get rid of the 4

Answer 16

How?

Answer 17

subtract ?

Answer 18

4y means 4 times y..

Answer 19

i have to divide

Answer 20

Bingo...and what ever you do to one side of the equation you have to do to the parts of the otherside of the equation so you divide both sides by 4 and what do you get?

Answer 21

-2 ?
