Question 1
1 / -0

y = 0 is the equation of

A
a line parallel to y-axis

B
y-axis

C
a line parallel to x-axis

D
x-axis

Solution

Explanation:

a x-intercept is a point on the graph where y is zero.
Question 2
1 / -0

x – 4 is the equation of

A
y-axis

B
a line parallel to x-axis

C
x-axis

D
a line parallel to y-axis

Solution

Explanation:

we know that the line parallel to y axis is given by x = a

x-4=0

x=4

so it is a line parallel to y axis, at a distance of 4 units from it, to the right.
Question 3
1 / -0

y + 7 is the equation of

A
x-axis

B
a line parallel to y-axis

C
a line parallel to x-axis

D
y-axis

Solution

Explanation:

y+7=0

y= -7

so the line is parallel to x axis and passing fom point y = -7
Question 4
1 / -0

The point of the form (a, a), where a lies on

A
the y-axis

B
the line x + y = 0

C
the x-axis

D
the line y = x

Solution

Explanation:

The point (a ,a ) lies on line x = y or x-y =0

here is the verification

Put x = a in equation

x-y =0

a-y = 0

-y = -a

y = a

hence it is prove that (a,a) is a solution of x- y =0 or x = y
Question 5
1 / -0

The point of the form (a, -a), where a lies on

A
the line y + x = 0

B
the y-axis

C
the line x = y

D
the x-axis

Solution

Explanation:

The point (a ,-a ) lies on line x+y =0

here is the verification

Put x = a in equation

x+y =0

a+y=0

y = -a

hence it is prove that (a,-a) is a solution of x+y =0
Question 6
1 / -0

The point of the form (-a, a), where a lies on

A
the line x + y = 0

B
the x-axis

C
the y-axis

D
the line y = x

Solution

Explanation:

The point (a ,-a ) lies on line x+y =0

here is the verification

Put x = a in equation

x+y =0

a+y=0

y = -a

hence it is prove that (a,-a) is a solution of x+y =0
Question 7
1 / -0

The graph of the linear equation 2x – 3y = 6, cuts the y-axis at the point

A
(0, -2)

B
(-2, 0)

C
(0, 2)

D
(2, 0)
Question 8
1 / -0

The graph of the linear equation 3x – 2y = 6, cuts the x-axis at the point

A
(0, 2)

B
(0, -2)

C
(-2, 0)

D
(2, 0)
Question 9
1 / -0

x = 0 is the equation of

A
a line parallel to y-axis

B
a line parallel to x-axis

C
x-axis

D
y-axis

Solution

Explanation:

x = 0 is a line of y axis

because x-coordinates of all points lie on y-axis are zero.
