Concept explainers
a.
To find variables in the graph.
a.
Answer to Problem 47MR
Distance and time.
Explanation of Solution
From graph we can clearly see that the distance from home is varyingwith time. So, thevariables in the graph are distance and time.
b.
To find the relation between the variables at various point on the graph.
b.
Explanation of Solution
Given:
Graph showing a family’s distance fron home as they drive to the mountain.
From the graph we can conclude that:
From OA graph show the linear variation between distance and time.
From AB graph show that distance is constant with time.
From BC graph show the linear variation between distance and time.
From CD graph show that distance is constant with time.
From DE graph show the linear variation between distance and time.
