In the first box, it gives the equation
In the second box,
When we substitute the given values of x in the equation, we will get the y value. We can verify the values for different values of x from the table.
In the third box,
It show the graph of the given function.
From the fourth box,
x represents the number of tickets and $0.25 represents the cost per ticket. and y represents the total cost.
Thus,
The given equation is a linear equation. It is in direct proportional.
Since, the given equation is linear. Therefore, we get a straingt line as a graph. This equation helps to find the total cost of tickets.
