Question

Using 1985 and 1995 as benchmarks, find a linear equation that can be used as a model to predict the number of active certified commercial pilots for any year. Assume a steady rate of decline

Answer 1

y2 -y1 / x2 -x1 = m
y = mx +c
sub in a value from graph and it's corresponding y value to find c

Answer 2

y2 = 1995
y1 = 1980
x2 = no of pilots in 1995
x1 = no of pilots in 1980

Answer 3

note: m = gradient of line
c = y intercept of line

Answer 4

is that the model im trying to predict the number of pilots in the year 2003
