Question 1.

Draw a line passing through (2, 3) and (3, 2). Write the coordinates of those points where this line intersecting the x-axis and y-axis.

Solution

Draw x-axis and y-axis. Write the points P (2, 3) and Q (3, 2). Join PQ and extend this line on both sides so that it can intersect x- axis on A and y-axis on B.

Then,

A → (5, 0)

B → (0, 5)

perimeter (in cm) | 16 | 20 | 24 | 28 |

Solution.

Question 10.

Draw a linear graph between time and, distance shown in the following table.

Time (hrs) | 3 | 6 | 9 | 12 | 15 |

Distance (in km) | 15 | 30 | 45 | 60 | 75 |

Solution:

Scale let

x-axis, 1 large division = 3 hours

y-axis, 1 large division = 10 km.

We obtain a linear graph by joining the points A(3, 15), B(6, 30), C(9, 45), D(12, 60) and E(15, 75).

Question 11.

Draw a linear graph between deposited money and interest earned given in following table.

Deposited money (in Rs) | 2000 | 4000 | 6000 | 8000 | 10000 |

Interest earned (in Rs) | 20 | 40 | 60 | 80 | 100 |

Solution

Scale let

x-axis, 1 large division = Rs 2,000 (sum deposited)

y-axis, 1 large division = Rs 10 (interest)

We obtain a linear graph by joining the points A(2000, 20), B(4000, 40), C(6000, 60), D(8000, 80) and E(10000, 100).
