Asked by guntursowmya57 | 16 Mar, 2021, 07:39: PM
Expert Answer
An equation gives a straight line when plotted on a graph is called as a Linear Equation.
In Linear equations the exponent/power on the variable is always 1.  
 
1. Linear Equation in one variable: An equation of the form ax + b = 0, where a, b are real numbers and x is a varible is called a Linear Equation in one variable.
Examples: 2x + 3 = 0,  y = 1,  4y - 8 = 0 etc
 
2. Linear Equation in two variables:
An equation of the form ax + by + c = 0, where a, b and c are real numbers, x and y are the variables is called a Linear Equation in two variable.
Examples: 2x + 3y + 1 = 0,  y + z = 1 etc

Two cell phone companies offer different packages. Company A charges a fixed monthly fees of  Rs 34 plus Rs 0.5/ minute talk time. Company B charges a fixed monthly fees of Rs 40 plus Rs  0.4 / minute talk time. Take x as the charges per minute for the talk time and y as the total amount. Based on above information answer the following question: (i) Linear equations representing the packages of a company A and B are : (a) y=34 + 0.5 x, y= 40 +0.4 x (b) y=34 + 0.4 x, y= 40 +0.5 x (c ) x=34 + 0.5 x, y= 40 +0.4 y (d) x=34 + 0.4y, y= 40 +0.5y (ii) If the average number of minutes used monthly by Sunil is 1160, then which of the  following is true? (a) Company A offers the better package (b)Company B offers the better  package (c ) Both companies offer the same package (d) None of the above (iii) If Sunita pays a total bill of Rs 208 to company B then the number of minutes used  by her : (a) 400  (b) 420 (c) 410 (d)390 (iv) The shape of the graph represented by the equations in part (i) is : (a) Rectangle (b) Circle (c) Parabola (d) Pair of lines (v) The number of minutes of talk time that results in equal monthly bills from both the  companies is : (a) 50  (b) 60  (c) 55  (d)65
