I need lots of help on slope! Find the slope and the y-intercept of the line

Answer:
Slope:6x
Y-intercept:-9
Step-by-step explanation:
first you move -6x to the other side so it can be 3y=6x-9
now you can refer to y=mx+b , mx is the slope and b is the y-intercept!
Slope formula states that y = mx + b where m is the slope, x is the variable and b is the y intercept
Rearrange the equation to look like the slope formula
-6x + 3y = -9 - - - - - 3y = 6x - 9 - - y = 6x/3 -9/3
Answer is y = 6x/3 -9/3
