We can clearly see line ‘a’ whose equation is y=mx+c. We can change the values of m and c using their corresponding slide bars. Observe how the position of this line changes as we change the values of m and c. Also observe how the angle α (between the line and the positive x-axis) changes with the change in values of m and c.
