Question
Find the cost to have your lawn mower for 2 hours.
- $16
- $17
- $18
- $19
Hint:
In direct variation, one quantity increases on the increase of another quantity.
The correct answer is: $18
$18 cost to have your lawn mower for 2 hours.
From the graph when mover 2 hours’ cost is $18.
Hence, the correct option is D.
The graph of a direct variation is a straight line.

The coordinates for the origin in the coordinate plane are________?
Since the origin is a reference point it will always be (0, 0). At any point which is represented as (a, 0) where ‘a’ arbitrary is any number will lie on the x-axis but not on the y-axis. Similarly, any point (0, b) where b is an arbitrary number will lie on the y-axis but not the x-axis. Also, any point (a, b) where a is an arbitrary number, as well as b, is an arbitrary number will not lie on the x-axis as well as the y-axis. Hence the intersection of the axis will have to be (0, 0).
