Equation of a line when its y intercept and slope are given

Summary: With the help activity in screen 3, we have learnt that: We will get a unique line if y intercept and slope of the line are given and the equation of the line will be y=mx+c where m is the slope of the line and c is the y-intercept. (Slope(m) = tan⁡α where α is the angle between the line and positive x axis.) To get a unique line we need two conditions. If only y intercept is given then we will get an infinite number of lines for different values of m and same will be the case when only slope m is given.
