NCERT Solutions for Class 8 Maths Chapter 15 Exercise 15.2 – Introduction to Graphs

1. Plot the following points on a graph sheet. Verify if they lie on a line

a) A(4, 0), B(4, 2), C(4, 6), D(4, 2.5)

Sol.:

NCERT Solutions for Class 8 Maths Chapter 15 Exercise 15.2 Question 1a

Yes, the points A, B, C and D lie on the same line.

b) P(1, 1), Q(2, 2), R(3, 3), S(4, 4)

Sol.:

NCERT Solutions for Class 8 Maths Chapter 15 Exercise 15.2 Question 1b

Yes, the points P, Q, R and S lie on the same line.

c) K(2, 3), L(5, 3), M(5, 5), N(2, 5)

Sol.:

NCERT Solutions for Class 8 Maths Chapter 15 Exercise 15.2 Question 1c

Hence, the points K, L, M and M are not lying on the same line.

2. Draw the line passing through (2, 3) and (3, 2). Find the coordinates of the points at which this line meets the x-axis and y-axis.

Sol.:

NCERT Solutions for Class 8 Maths Chapter 15 Exercise 15.2 Question 2

The line meets x-axis at P(5,0) and y-axis at Q(0,5).




3. Write the coordinates of the vertices of each of these adjoining figures.

Sol.:

NCERT Solutions for Class 8 Maths Chapter 15 Exercise 15.2 Question 3

The coordinates of the vertices of each of these adjoining figures
A(2, 0), B(2, 3), C(0, 3) and O(0, 0)
P(4, 3), Q(6, 1), R(6, 5) and S(4, 7)
K(10, 5), L(7, 7) and M(10, 8)

4. State whether True or False. Correct that are false.

i) A point whose x coordinate is zero and y-coordinate is non-zero will lie on the y-axis.
Sol.: – True.

ii) A point whose y coordinate is zero and x-coordinate is 5 will lie on y-axis.
Sol.: – False. As the point (5,0) will lie on x-axis.

iii) The coordinates of the origin are (0, 0).
Sol.: – True.
