Using the graph of the linear equation, the average cost per pound is $1.3
<h3>Graph of Linear Equation</h3>
The graph of the linear equation is a set of points in the coordinate plane that all are solutions to the equation. If all variables represent real numbers one can graph the equation by plotting enough points to recognize a pattern and then connect the points to include all points.
To find the estimate the cost per pound, we can find the slope of the line which is calculated as;
m = y₂ - y₁ / x₂ - x₁
m = 13 - 5 / 10 - 4
m = 8 / 6
m = 1.3
The cost per pound is approximately 1.3 dollar
