Put -3x-y=9 in slope intercept form

Question

How do I put -3x-y=9 in slope intercept??

Answer 1

-3x -y =9

add 3x on both sides,

-3x-y +3x=9+3x

-y =9+3x

Multiply both the sides by -1,

y=-3x-9

Slope-intercept form of a line,

y= -3x-9

Slope intercept form: y=mx +b  where m= slope, b= y-intercept.

Answer 2

-3x - y = 9

 

-3x - y - 9 = 0

 

-3x - 9 = y

 

y = -3x - 9 = -3x + -9 is the line in slope intercept form.

The slope M=-3 and the intercept B=-9
