Answer:

Step-by-step explanation:
Given
The attached graph
Required
Determine the linear equation
First, we need to calculate the slope

From the graph, the following relationships exist:


So, the expression for calculating slope becomes:




Next, we calculate the equation using:

This gives:

Open bracket

Make y the subject:
