1. Equation of a line which is 5 units distance above the x-axis is

x = 5

x + 5 = y

y - 5

x - y = 0

2. x = 3 and y = -2 is a solution of the equation 4px - 3y = 12, then the value of p is

\(\frac{1}{2}\)

3. Which of the following is the equation of a line parallel to y-axis?

y = 0

x + y = z

y = x

x = a

4. Any point on the line y = 3x is of the form

(a, 3a)

(3a, a)

(a, \(\frac{a}{3}\)

(\(\frac{a}{3}\), -a)

5. To which equation does the graph represent? MCQ Questions for Class 9 Maths Chapter 4 Linear Equations for Two Variables with Answers

3x - 7y = 10

y - 2x = 3

8y - 6x = 4

5x +\(\frac{35}{2}\)y = 25

6. Any point of the form (a, - a) always lie on the graph of the equation

x = -a

y = a

y = x
