Straight Lines

In this program student will learn mainly about straight line and graphs which is one of the important topic in context with co-ordinate geometry. Brief recall of two dimensional geometry from earlier classes. Shifting of origin. Slope of a line and angle between two lines. Various forms of equations of a line: parallel to axis, point-slope form, slope-intercept form, two-point form, intercept form and normal form. General equation of a line. Equation of family of lines passing through the point of intersection of two lines. Distance of a point from a line. These are the main points where we will focus in this program.
