You can put this solution on YOUR website! 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.
