Plot(x, y) When you run the file, MATLAB displays the following plot − Let us take one more example to plot the function y = x 29 Use graph paper for this question (i) Draw the graphs of 3x y – 2 = 0 and 2x y – 8 = 0 Take 1 cm = 1 unit on both axes and plot three points per line (ii) Write down the coordinates of the point of intersection and the area of the triangle formed by the lines and the xaxisGiven the unique solution of equation is x = 2 and y = 3 Put the value of x and y in each of the given equations to check if these values satisfy the equations (A) xy = 1 ,We get 23 = 5 = 1 2x3y =5 2×23×3 = 49 = 13 = 5 (B) 2x5y = 11 2×25×3 = 415= 19 = 11 4x10y = 22
