Question

you went to market with your father and purchase 1 kg Mango and 1kg apple.the cost of apple was two times the cost of mango represent it in linear equation in two variables and draw its graph​

Answer 1

Given:

After going to the market, you and your father purchased 1 kg mango and 1 kg apple

Cost of apple is 2 times the cost of mango

To find:

Represent the given situation as a linear equation in two variables and draw its graph

Solution:

Finding the linear equation for the given situation:

Let's assume,

"x" → represents the cost of 1 kg mango

"y" → represents the cost of 1 kg apple

Now, according to the question, we can write the linear equation representing the given situation as follows:

$\boxed{\bold{\underline{y = 2x}}}$

Plotting the graph:

Depending on the above linear equation, we will now create a table and then plot a graph based on that:

Equation: y = 2x

Table:

x  |  0  |   50   |  100  |  200

---------------------------------------

y  |  0  |  100  |  200  |  400

Graph:

• Mark the points (50, 100), (100, 200) & (200, 400) on the graph paper.
• Join the points together to form a line representing the linear equation y = 2x (just as shown in the graph attached below)

Note: Graph is plotted and attached below
