You can put this solution on YOUR website!
you have to solve for y in order to place the equation into y = mx + b form.
start with:
3x = 9 + 3y
subtract 9 from both sides of the equation to get:
3x - 9 = 3y
divide both sides of the equation by 3 to get:
3x/3 - 9/3 = y
simplify to get:
x - 3 = y
if x - 3 = y, then y = x - 3
y = x - 3 is the y = mx + b form.
m is equal to 1 (coefficient of x)
b is equal to -3 (constant term)
m is the slope of the equation.
b is the y-intercept of the equation.
this means the slope of your equation is equal to 1 and the y-intercept of your equation is equal to -3.
