(i) Is it a linear graph?

(ii) Is it a linear graph?

Write the coordinates of each of the vertices of each polygon in Fig. 27.9.

A courier-person cycles from a town to a neighbouring suburban area to deliver aparcel to a merchant. His distance from the town at different times is shown by thefollowing graph.

A. What is the scale taken for the time axis?

B. How much time did the person take for the travel?

C. How far is the place of the merchant from the town?

D. Did the person stop on his way? Explain.

E. During which period did he ride fastest?

Locate the points A (1, 2), B (4, 2) and C (1, 4) on a graph sheet taking suitable axes. Write the coordinates of the fourth point D to complete the rectangle ABCD.

Plot the points (2,4) and (4,2) on a graph paper, then draw a line segment joining these two points.

Extend the line segment on both sides to meet the coordinate axes. What are the coordinates of the points where this line meets the x-axis and the y-axis?
