We will investigate the formulation of an equation of a straight line.
All equation of a straight line are mostly expressed in the general slope-intercept form as follows:

Where,

The above two parameters ( m and c ) distinguish amoung different equation of a straight line.
We are given the values of the two parameters as follows:

We will go ahead and plug in the respective values of the two parameters in the generalized formulation of an equation of a straight line:

Therefore, the equation of the straight line is:
