Question:
Find an example from your line of work or daily life that can be expressed as a linear equation with two variables. Graph this equation.

Answer:
Example.
Ann's father's age is 7 years more than 3 times Ann's age. Express this statement an a linear equation and also graph the equation.

Solution:
Suppose Ann's age = x years.

Suppose Ann's father's age = y years.

Three times Ann's age = 3x

7 years more than 3 times Ann's age = 3x + 7

Then we can write, y = 3x + 7, which is a linear equation in two variables.

To graph the equation, put some arbitrary values for x and then find out the corresponding values of y as follows.

When, x = 1, y = 3*1 + 7 = 10

When, x = 0, y = 3*0 + 7 = 7

When, x = 2, y = 3*2 + 7 = 13

When, x = -1, y = 3*-1 + 7 = 4

and so on.

Now plot these points on a graph paper.

Then the graph will come likes this....

Hope you found the explanation useful.
