Which function below has the lowest y-intercept?

f(x)

graph going through (0,5) and (4, 3)
g(x)

kyle started the summer having read 3 books but plans to read 6 books per month over the summer.

h(x)

h(x) = 3x + 4

f(x)

g(x)

h(x)

the functions all have the same y-intercept.

If f(x) is given with points (0,5) and (4,3), it can be easily plotted in a coordinate system (see .jpeg image in attachment).
If g(x) is a function defined by text:
Kyle started the summer having read 3 books but plans to read 6 books per month over the summer.
Then, g(x) is given with:
g(x) = 6*x+3 (3 books read already, and 6 books will be read each month).
h(x) is already given with:
h(x)=3*x+4
These all three functions are plotted in coordinate system (see the .jpeg image), and it can be seen that the lowest y-intercept has function g(x), and it is the value of 3 on y-axis. Others have 4 (h(x)) and 5 (f(x)).
