Finding the slope of a line from an equation is simple. If the equation is already in slope intercept form, then the m variable is the slope. If it isn't in slope intercept form, rearrange the equation to solve for m, and plug in the given variables to find the slope.

**Place the equation in slope intercept form**The first step in determining the slope of an equation is to rearrange the equation in the slope intercept form. The slope intercept equation is y = mx+b, where m is the slope, b is the y-intercept, and x and y are points in the line.

**Solve for m**If the y-intercept and a set of points are given, then solve for m to find the slope of the line. Plug the y-intercept, the x point and the y point into the slope intercept equation, and solve for m.

**Check the answer**After solving for m, check the answer by graphing the line. Place the x and y points on a graph, and plot a point at the y-intercept. Connect the points to create a line. Check the slope of the line by choosing two new x and y points and plugging them and the y-intercept into the slope intercept equation.
