Equation of a line when a point n slope are given

We can clearly see a line ‘a’ whose equation is y=mx +c. We can change the values of m (slope of this line) and \(x_1, y_1)\), the co-ordinates of the given point A through which this line passes using their corresponding slide bars. Observe how the position of this line changes as we change the values of m, \(x_1\) and \(y_1\).
