Explanation:

Step1: Isolate the variable y

Add 4 to both sides of the inequality $y - 4>-6$. We get $y-4 + 4>-6 + 4$, which simplifies to $y>-2$.

Answer:

1. $(-2, oo)$
2. On the number - line, we use an open - circle at $-2$ (because $y$ is strictly greater than $-2$, not equal to it) and draw an arrow to the right to represent all the numbers greater than $-2$.
