An investment is worth $3127 in 1994. By 1998 it has grown to $3663. Let y be the value of the investment in the year x, where x=0 represents 1994. Write a linear equation that models the value of the investment in the year x. please help! thaaaanks!

Hi Laney, to know the change in a year divide, delta Y into delta x
=(3127-3663)/(1998-1994)
=134
There is an increase of 134 every year
Therefor, for year x, the value of Y(investment) is 3127 and 134x
I.e. Y=3127+134x
=(3127-3663)/(1998-1994)
=134
There is an increase of 134 every year
Therefor, for year x, the value of Y(investment) is 3127 and 134x
I.e. Y=3127+134x
