**(a) always coincident**

**(b) parallel**

**(c) always intersecting**

**(d) intersecting or coincident**

(d) If a pair of Linear Equations is consistent the two lines represented by these equations have a solution, this implies that either line is intersecting or coincident.

**3. What is a Linear Equation as taught in Chapter 3 of CBSE Class 10?**

A Linear Equation is defined as an equation with a maximum degree of 1. This means that in a Linear Equation, no variable has an exponent greater than 1. A Linear Equation's graph is always a straight line. The standard form of a Linear Equation in one variable is of the form Ax + B = 0. Here, x is a variable, and A and B are constants.

4. A shopkeeper gives books on rent for reading to students. He takes a fixed charge for the two days and an additional charge for each day thereafter. Rima paid Rupees 22 for a book kept for six days, while Ruchi paid Rupees 16 for the book kept for four days, then what will be the charge for an extra day?

(A) Rupees 5

(B) Rupees 4

(C) Rupees 3

(D) Rupees 2

(C)

Explanation: Let Rupees x be the fixed charge and Rupees y be the charge for each extra day.

Then by the given conditions

x + 4y = 22 …..(i)

x + 2y = 16 …..(ii)

Subtracting equation (ii) from (i), we get: y = Rupees 3
