There are number of forms of the equation of a line like the intercept form, the general equation of a line, the normalized equation, the Point slope equation, Slope intercept equation etc.The equation of a standard line is given asy = m x + c, where â€˜mâ€™ refers to the Slope of a line and â€˜câ€™ refers the value of the y- intercept.While finding the equations of lines we only needed to calculate the parameters â€˜mâ€™ and â€˜câ€™. The value of â€˜câ€™ can be calculated easily we just need to see that where the line crosses the y- axis. To calculate the slopes of the equation of line just need to remember the formula shown below:

m = change in the â€˜yâ€™ parameter / change in the â€˜xâ€™ parameters = rise / run.
