In two or more complete sentences describe the process in writing the equation of a line given two points.

Let () and () be two points belonging to a line, then from these two points we can find the equation of the line of the form

y = mx + b

where m is the slope and b is the cut point with the y axis.

the slope of the line is found with the following formula.

To find b substitute and in the equation and clear b. (You can also replace and )

After finding the value of m and b, you already have the necessary parameters to write the equation of the line y = mx + b

the answer is 13 cm
