lesson#11 br How to write equation of straight line? (2) br How to write the equation of a slant line (non-vertical and non-horizontal line)? br CASE-1: If slope and y-intercept of a non-vertical line are given, we will use br Slope-intercept from: y=mx+c br here m=slope and c=y-intercept br Math Ex 4.3 Part 11 br Slope Intercept From of Equation of Straight Line. br Theorem: Equation of a non-vertical straight line with slope "m" and y-intercept "c" is given by br y=mx+c br SPECIAL NOTE: If the line passes through origin then c=0 br Equation will become y=mx br Math Ex 4.3 Part 11 br CASE-2: If a point and slope of a non vertical line are given, we will use br Point-Slope from: y-y1=m(x-x1) br here (x1-y1) is given point and "m" is slope. br Introduction to Analytical Geometry br Chapter No 4 br Exercise No 4.
