The slope-intercept form of the equation of a straight line is given to be:

where m is the slope and b is the intercept on the y-axis.
The slope is calculated using two points on the line by the formula:

Therefore, for this line, the slope will be:

Therefore, this value for the slope is substituted back into the equation for the line:

At the point (6, 0), we can calculate the value of b to be:

Therefore, the equation is:
