Please find the x-intercept and y-intercept from these

To find the x-intercept, set $y=0$.

$$0 = -2$$

This is a false statement, which means the line $y=-2$ never crosses the x-axis.

• The x-intercept does not exist.

To find the y-intercept, set $x=0$.
The equation $y=-2$ does not depend on $x$. Therefore, when $x=0$, $y$ is still $-2$.

• The y-intercept is $\boxed{(0, -2)}$.

For the equation $x = 3$:

To find the x-intercept, set $y=0$.
The equation $x=3$ does not depend on $y$. Therefore, when $y=0$, $x$ is still 3.

• The x-intercept is $\boxed{(3, 0)}$.

To find the y-intercept, set $x=0$.

$$0 = 3$$

This is a false statement, which means the line $x=3$ never crosses the y-axis.

• The y-intercept does not exist.

For the equation $y = x$:

To find the x-intercept, set $y=0$.

$$0 = x$$

• The x-intercept is $\boxed{(0, 0)}$.

To find the y-intercept, set $x=0$.

$$y = 0$$

• The y-intercept is $\boxed{(0, 0)}$.
