x >= 80
y=2


Explanation
Step 1
The y -intercept of a graph is the point where the graph crosses the y -axis.
so , let's check the graph
therefore, the y-intercept is 2
Step 2
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero)
hence, the function is potive in ( in x axis)

Step 3

Answer:
A) The number line goes from negative 8 to positive 8. At 0, there is an open circle. The number line is shaded to the left of 0 and on the left end of the shaded line there is a left-facing arrow.
Step-by-step explanation:
Given inequality: x < 0
open circle: < or >
filled circle: ≤ or ≥
Therefore, for x < 0 there will be an open circle at 0.
< means less than, so the number line will be shaded to the left of 0 and there will be a left-facing arrow on the end of the shaded line.
