Answer:
y = 1/3x - 8
Step-by-step 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 )
