Question

Hari sells vacuum cleaners. Each week he is paid a Basic salary of Rs. 5000 plus Rs. 500 for each vacuum cleaner that he sells.
i. This an example of (a) Linear equation in 2 variables (b) Quadratic polynomial (c) Quadratic Equation (d) None of these ii.
ii. What is the graphical representation of above information?
(a) Straight Line (b) a point (c) Parabola (d) None of these iii.
​

Answer 1

Answer:

Let the total amount he gets =y and the number of cleaners he sells =x, then algebraically this can be represented by:

y=5000+500x

This is a linear equation in two variables x and y

Actually 5000 and 500 are constant.

So in general it can be written as

y=a+bx where a and b are constant
