1. a) Linear equation in 2 variables.
2. a) straight line

Answer 2

Answer:

(i) (d) None of these

(ii) (a) straight line

Step-by-step explanation:

Here, we just need to consider one variable for number of vacuum cleaners.

Let the number of vacuum cleaners sold be x.

So, the equation for basic salary will be

                     $5000+500x$

Hence, this is a linear equation in one variable.

Since, the equation depends on x, i.e. one degree variable

Therefore, the graph for this equation is a straight line
