Linear Equations in Two Variables - Test Papers
CBSE Test Paper 01 CH-4 Linear Equations in Two Variables For what value of ‘k’, x = 2 and y = -1 is a solution of x + 3y – k = 0? 2 -2 -1 1 If we divide both sides of a linear equation with a non-zero number, then the solution of the linear equation changes remains the same none of these gets divided by the number If the line represented by the equation 3x + ky = 9 passes through the points (2, 3), then the value of ‘k’ is 2 1 3 4 How many linear equations in ‘x’ and ‘y’ can be satisfied by x = 2, y = 3? only one none of these many two The graph of the linear equation y = 3x passes through the point (0 , − 2 3 − 2 3 ) ( − 2 3 − 2 3 , 0) (0 , 2 3 2 3 ) ( 2 3 2 3 , 2) Fill in the blanks: y + 7 is the equation of a line parallel to _________ Fill in the blanks: The equation of X-axis is ________. If x = 1, y = 2 is a solution of the equation a 2 x + ay = 3, then find the values of a. Arvind and Vinod have some erasers. Arvind said to Vinod, if you will give me 10 e...
