Solve your equation for which is to say rearrange the equation according to the rules of algebra for linear equations so that it takes the form:
Once you have done that, the coefficient on (that is the value ) is the slope and the constant term, , is the -coordinate of the intercept,
Note that the -intercept is a point in and must be specified as an ordered pair. The fact that the point is an -intercept demands that the -coordinate be equal to zero.
