The data in the table
Solving (a): The coordinate that represents the unit rate
The unit rate is when its 1 pound
This is so because the unit rate is dollars per pounds.
<em>Hence, the coordinate is </em><em></em>
Solving (b): Equation of the graph
First, we calculate the slope (m)
Where:
The equation is then calculated as thus:
This gives:
Make y the subject
<em>Hence, the equation of the graph is: </em><em></em>
