What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

John bought X burgers and Y French fries.

Expression for Peter's food items = Y - 9 + 5X  or

= 5X + Y - 9

Thus, the expression 5X + Y - 9 represents the Peter's food items if Peter bought 9 less French fries than John but 5 times as many as burgers option (C) is correct.
