Write a linear equation which satisfies this data.

(You may take their contributions as Rs. x and Rs. y.) Draw the graph of the same.

Answer :

Let the contributions of Yamini and Fatima together towards the Prime Minster’s Relief Fund to help the earthquake victms are Rs. x and Rs. y, respectively.

Then, by given condition, x + y = 100 … (i)

x | 0 | 100 |
---|---|---|

y = 100 - x | 100 | 0 |

(x, y) | B (0, 100) | A (100, 0) |

Here, we plot the points B (0, 100) and A (100, 0) on graph paper and join all these points to form a line AB.

- Draw the graph of each of the following linear equations in two variables i) x + y = 4 ii) x - y = 2 iii) y = 3x iv) 3 = 2x + y
- Give the equations of two lines passing through (2, 14). How many more such lines are there, and why?
- If the point (3, 4) lies on the graph of the equation 3y - ax - 7 , find the value of a .
- The taxi fare in a city is as follows:For the first kilometer, the fare is Rs. 8 and for the subsequent distance it is Rs. 5 per km. Taking the distance covered as x km and the total fare as Rs. y, write a linear equation for this information and draw its graph.
- From the choices given below, choose the equation whose graphs are given in fig. (a) and fig. (b). For fig. (a)For fig. (b)i) y = x (i) y = x + 2ii)x + y = 0y = x - 2iii)y = 2xy = -x + 2iv)2 + 3y = 7xiv)x + 2y = 6
- If the work done by a body on application of a constant force is directly proportional to the distance travelled by the body, express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as 5 units. Also, read from the graph the work done when the distance travelled by the body is (i) 2 units (ii) 0 units.
- In countries like USA and Canada, temperature is measured in Fahrenheit, whereas in countries like India, it is measured in Celsius. Here is linear equation that converts Fahrenheit to Celsius. F = (\(\frac{9}{5} \) )C + 32 (i) Draw the graph of the linear equation above using Celsius for x-axis and Fahrenheit for y-axis. (ii) If the temperature is \(30^{\circ}\)C , what is the temperature in Fahrenheit? (iii) If the temperature is 95F , what is the temperature in Celsius? (iv) If the temperature is \(0^{\circ}\)C , what is the temperature in Fahrenheit and if the temperature is 0F , what is the temperature in Celsius? (v) Is there a temperature which is numerically the same in both Fahrenheit and Celsius? If yes, find it.
