you will want to set up equation in slope-intercept form y=mx+b
i subtracted 15
i divided by 3
this is in the correct form so now u can see where m=slope and b=yintercept
so and

To find the slope of each line, you will need to change each equation into slope intercept form: y = mx + b
m = slope, b = y-intercept
For the example you provided: 15 + 3y = 4x
First, you would get 3y by itself by subtracting the 15 from the left and right side of the equation.

Now, you want to get 'y' completely by itself by dividing 3 into itself and each term on the right side of the equation.

Simplify:

Now, you found the value of m, slope, which equals (4/3)

Solve the equation for in terms of everything else. That is to say do whatever is necessary to put the equation in the following form:



Once you have done that, the slope is whatever the coefficient on (the in the equation above) turns out to be.

Your example:



Add to both sides:



Multiply both sides by



And there is the slope staring you right in the face right next to the .
