Question

An auto driver has a fixed charge of Rs . 50 and then charges Rs .10 per kilometer . Draw a conversation graph and estimate fare for a ride of 10 km .​

Answer 1

Answer:

y=20+(Total distance−1)12 [(Total distance-1), As 1

st

kilometer is charged at Rs.20]

y=20+(x−1)12

y=12x+8

when x=16, y=200

Answer 2

Answer:

Let the total distance be x km

and total cost be y

now, 10rs for 1st km, and 4Rs. per km for rest

so,

y=1(10)+4(x-1)

y=4x+6,

sub,

x=-2,y=-2

x=-1, y=2

so plot points (-2,-2),(-1,2)

scale : 1cm = 1 unit on both axis

linear equation
