To change the equation y = 23x − 4 to y = 23x, we need to only keep the coefficient of x and remove the constant term. This means that the transformation required is to shift the graph up by 4 units.
For the second question, to make the situation non-proportional, the company would need to charge a flat rate of $10 and then charge $8 per mile. This would create a situation where the cost is not directly proportional to the distance traveled.
