Question

Thank you in advance.

Answer 1

y = 1/3x - 8

Explanation:

First you solve:

3x + y = - 5

Then subtract x since we're looking for y on both sides of the ( = ):

3x + y = - 5

-3x -3x

Making it:

y = -3x - 5

and then you make the slope ( m ) positive , like so :

1/3

then set up the equation :

y - y1 = m ( x - x1 )

and fill in the points they gave you :

( 3, -7 )

^x1 ^y1

Like this :

y - y1 = m ( x - x1 )

y + 7 = 1/3 ( x - 3 )

y + 7 = 1/3x - 1

-7 -7

y = 1/3x - 8

( If you have the calculator for it , you could always put the equation in and check if it goes through the point )
