Line graph and Linear graph

Explain the situation represented by the following distance-time graph :

• Rest position then moves with uniform speed.

• Moves with uniform speed and then comes to rest.

• Graph shows the uniform speed.

• Graph shows the increasing speed.

Plot a line graph for the variables p and q, where p is four times q, i.e., the equation is p = 4 q.

Using the graph, find the value of (i) p, when q = 4 and (ii) q, when p = 20.

• (i) p = 16 and (ii) q = 5

• (i) p = 24 and (ii) q = 5

• (i) p = 26 and (ii) q = 25

• (i) p = 16 and (ii) q = 15

Consider the following input/output table. Draw a line graph for it.

Now, use the graph drawn to predict the outputs for the inputs of 3 and 8, respectively.

• 8 & 23

• 8 & 3

• 18 & 23

• 48 & 33

Seema starts off from home at 7 a.m. with her father on a scooter that goes at a uniform speed of 30 km/hr. Her father drops her at her school after half an hour. She stays in the school till 1.30 p.m. and takes an autorickshaw to return home. The autorickshaw has a uniform speed of 10 km/hr. Determine the distance of Seema's school from her home.

• 50 km

• 16 km

• 15 km

• 56 km
