LINEAR EQUATIONS IN TWO VARIABLES
www.ncert.nic.inThis is an example of a linear equation in two variables. It is customary to denote the variables in such equations by x and y, but other letters may also be used. Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, πu + 5v = 9 and 3 = 2 x – 7y. Note that you can put these equations in the form 1.2s + 3t – 5 = 0,

If lines are drawn parallel to the line of regression at distances equal to ± (S scatter)0.5 above and below the line, measured in the y direction, about 68% of the observation should
