The cost ofof two pizza and one burger is rupees 450.This situation as a linear equation in two variable and also draw a graph.

Dear student,

Let the cost of the 2 pizzas be Rs ' 2x ' and the cost of 1 burger Rs ' y '.

So, according to the given conditions,

2x + y = 450.

You can plot the graph according to the following:

If x = 0, y = 450. So, (0, 450) is a solution of the equation.

If y=0, 2x = 450, which gives x = 225. So (225,0) is one  of its solutions.

By joining these two points, we get the graph.
 

Regards
