OBJECTIVE TYPE QUESTIONS WORKSHEET LINEAR EQUATIONS IN TWO VARIABLES Answer the following questions: (1) What is the equation of the line parallel to x-axis? (2) What is the equation of the line parallel to y-axis? (3) Which type of graph of a linear equation ax + by + c = 0 is? (4) How many solutions of a linear equation in one variable are there? (5) How many solutions of a linear equation in two variable are there? (6) What is the equation of the x-axis? (7) What is the equation of the y-axis? (8) Without drawing the graph of the equation, find the points at which the straight line represented by equation 4x + 5y = 30 cuts the x-axis and the y-axis. (9) For what value of k, the point (k, -3) is a solution of 3x + 4y = 12? (10) Write the equation of the line which is parallel to the y-axis at the distance 4 units from the origin and on the right of the y-axis. (11) Write the points at which the equation ax + by = c cuts the coordinate axes. True or False: Justify your answer. (12) The graph of the equation y = 1 is a line parallel to y-axis. (13) A linear equation of the form ax + by = 0 always passes through the origin. (14) A linear equation in two variables has only two solutions. (15) (3, 0) is a solution of the equation 2x – 3y = 6.
