To find the slope of a line in standard form, convert the line to slope intercept form. In slope intercept form, y = mx+b, m is the slope.

Write the equation in slopeintercept form
The first step in finding the slope of a line that is written in standard form is to write the equation in slopeintercept form, y=mx+b. To do this, rearrange the variables. The standard form, Ax + By = C can be rewritten as By = Ax + C.

Divide by B to simplify
In the equation By = Ax + C, B needs to be distributed through the equation. To do this, divide both sides by B. The answer is y = (A/B)x + C/B.

Find the slope
Once the equation of the line is in slopeintercept form and is simplified, then the slope equals the term in front of the x variable. In the standard form from step 2, the slope is A/B.
