Why we did x-1 in ex 4.3 ques 4 |
| Answer» Total distance covered = xTotal fare = yFare for the first kilometer = 8 per kmFare after the first 1km = 5 per kmIf x is the total distance, then the distance after one km = (x-1)kmi.e., Fare after the first km = 5(x-1)According to the question,The total fare = Fare of first km+ fare after the first kmy = 8+5(x-1)y = 8+5(x-1)y = 8+5x – 5y = 5x+3Solving the equation,When x = 0,y = 5x+3y = 5×0+3y = 3When y = 0,y = 5x+3o = 5x+35x = -3x = -3/5\txy03-3/50\tThe points to be plotted are (0, 3) and (-3/5, 0) | |
