Question 1
1 / -0

The graph of every linear equation in two variables is a

A
straight line

B
curve

C
circle

D
square

Solution

because for one value of one variable their is only one and unique value of other variable
Question 2
1 / -0

The equation x = 7 in two variables can be written as

A
0.x + 1.y = 7

B
1.x + 0.y = 7

C
0.x + 0.y = 7

D
1.x + 1.y = 7

Solution

The equation x = 7 in two variables can be written as exactly 1.x + 0.y = 7

because it contain two variable x and y and coefficient of y is zero as there is no term containing y

in equation x = 7
Question 3
1 / -0

If we multiply both sides of a linear equation with a non-zero number, then the solution of the linear equation

A
gets multiplied by the number

B
remains the same

C
changes

D
none of these

Solution

If for any c. where c is any natural number

Like addition and subtraction we can multiply and divide both sides of an equation by a number, c, without changing the equation, where c is any natural number.
Question 4
1 / -0

If we divide both sides of a linear equation with a non-zero number, then the solution of the linear equation

A
gets divided by the number

B
changes

C
remains the same

D
none of these

Solution

If then for any non-zero c. We can divide both sides of an equation by a non-zero number c, without changing the equation.
Question 5
1 / -0

If the point (3, 4) lies on the graph of 3y = ax + 6, then the value of ‘a’ is

A
0

B
1

C
2

D
3

Solution

the point (3, 4) lies on the graph of 3y = ax + 6

so it will satisfy the equation
3 y = a x + 6
3 (y) = a x + 6
12 = 3a + 6
12 - 6 = 3a
3a = 6
a = 6/3

a=2
