Find the x-intercept by setting f(x) = 0.

$$
0 = x - 4
$$
$$
x = 4
$$
The x-intercept is $(4, 0)$.

$$
f(0) = 0 - 4
$$
$$
f(0) = -4
$$
The y-intercept is $(0, -4)$.  
The intercepts are $\boxed{x\text{-intercept: } (4, 0), y\text{-intercept: } (0, -4)}$.

$$
0 = 4x + 8
$$
$$
4x = -8
$$
$$
x = -2
$$
The x-intercept is $(-2, 0)$.

$$
g(0) = 4(0) + 8
$$
$$
g(0) = 8
$$
The y-intercept is $(0, 8)$.  
The intercepts are $\boxed{x\text{-intercept: } (-2, 0), y\text{-intercept: } (0, 8)}$.

$$
0 = \frac{3}{5}x - 3
$$
$$
\frac{3}{5}x = 3
$$
$$
3x = 15
$$
$$
x = 5
$$
The x-intercept is $(5, 0)$.

$$
y = \frac{3}{5}(0) - 3
$$
$$
y = -3
$$
The y-intercept is $(0, -3)$.  
The intercepts are $\boxed{x\text{-intercept: } (5, 0), y\text{-intercept: } (0, -3)}$.

The x-intercept is where the line crosses the x-axis.  
The x-intercept is $(2, 0)$.

Since $x=2$ is a vertical line, it is parallel to the y-axis and never crosses it.  
There is no y-intercept.  
The intercepts are $\boxed{x\text{-intercept: } (2, 0), \text{no y-intercept}}$.

The x-intercept is where the line crosses the x-axis.  
Since $y=-3$ is a horizontal line, it is parallel to the x-axis and never crosses it.  
There is no x-intercept.

The y-intercept is $(0, -3)$.  
The intercepts are $\boxed{\text{no x-intercept}, y\text{-intercept: } (0, -3)}$.

$$
5x - 2(0) = 10
$$
$$
5x = 10
$$
$$
x = 2
$$
The x-intercept is $(2, 0)$.

$$
5(0) - 2y = 10
$$
$$
-2y = 10
$$
$$
y = -5
$$
The y-intercept is $(0, -5)$.  
The intercepts are $\boxed{x\text{-intercept: } (2, 0), y\text{-intercept: } (0, -5)}$.
