I get
y-1= 7/3 (x+1)
or
y = 7/3x + 10/3.

I have entered in both of these answers and I always get the question wrong. Can anyone help me understand what I am doing wrong?

I kind of just now figured this out, but the scale of the y axis doesn’t increase by one, try entering in the intercept values into the exponential equation. --> f(x)=2^x
