y=14.94x+109.5. where x represents the number of years after 2000
y represents the number of mobile
Y intercept is the value when number of years x is 2000
It means y intercept is the value when x=0
To find y intercept , we plug in 0 for x
y=14.94x+109.5
y=14.94(0)+109.5
y = 109.5
y intercept is (0,109.5)
The number of mobile is 109.5 in the year 2000
