Subject: Maths. 1) Draw the graphs of linear equations y=x and y=-x on the same cartesian plane. What do you observe? 2) Determine the point on the graph of the linear equation 2x + 5y = 19, whose 1 ordinate is 1 times its abscissa. 3) Draw the graph of the equation represented by a straight line which is parallel to the x- axis and at distance 3 units below it. 4) Draw the graph of the linear equation whose solutions are represented by the Page 1 of 3 points having the sum of the coordinates as 10 units. 5) Write the linear equation such that each point on its graph has an ordinate 3 times its abscissa. 6) If the point (3, 4) lies on the graph of 3y = ax +7, then find the value of a. 7) How many solution(s) of the equation 2x+1-x-3 are there on the (1) Number line (ii) Cartesian plane 8) Find the solution of the linear equation x + 2y = 8 which represents a point on (i) x-axis (ii) y-axis 9) For what value of c, the linear equation 2x + cy= 8 has equal values of x and y for its solution. 10) Let y varies directly as x. If y 12 when x = 4, then write a linear equation. What is the value of y when x = 5?
