The graph of both modelling equations using a common coordinate system has been attached to this answer.
From the given table, we see that;
- In 1970; The sales price was;
In Seattle = $38000
In Port Townsend = $84000
- In 1990; The sales price was;
In Seattle = $8400
In Port Townsend = $168400
- Now, to draw a graph that will model the equations that will arise from the given table, we will make the y-axis to be the amount of sales price while the x-axis will be the year of the sales price.
The red line on the attached graph represents the line for Port Townsend while the blue line represents Seattle.
