convert the equation to the y = mx + b form. m in this form equals the slope. m= 1/2

To convert the equation to the y = mx + b, y must be isolated by itself.

Start by subtracting 3x from both sides of the equation.

#3x - 3x - 6y = - 3x + 12# This gives

# - 6y = -3x + 12# Now divide both sides by -6

#( -6/-6) xx y = (-3/-6) xx x + 12/-6# The equation is now

# y = 1/2 x - 2 #

m = 1/2 is the slope.
