Is each situation a linear or a nonlinear model?
A home’s value is given by the equation y = 154,000(1.04)x, where y is the value of the house and x is the number of years since the home was purchased.

it is definitely not a line
a line looks like \(y=mx+b\)
what you have there is an "exponential" model
the variable is in the exponent

Is this >> y = 154,000(1.04)x supposed to be y = 154,000(1.04)^x ?
Yeah sorry :)
It is not linear. If it were, the x would appear as x to the first power.
Okay Thanks :) I only have two more now.
The graph of this: y = 154,000(1.04)^x
is not a line.
Linear looks like y = 5x + 2.
The big deal is that the x is not raised to a power such as 2 and the x is not an exponent.
You can always graph the function and look and see if the graph is a line.
Oh ok I think my last two might be linear then @Directrix
The amount of money Elijah has in his bank account is given by the equation B = 1400 + 120m, where B is the balance in his account and m is the number of months since he opened the account.
The number of words Sarah can type in a given amount of time is given by the equation w = 32m, where w is the number of words and m is the number of minutes she types.
1 looks like it, and maybe 2?
I agree with you that both are linear.
No exponents, no powers.
