When the y-intercept is positive, where does the line cross the y-axis on the graph? When it is negative?

1. 0,0

2. negative 1

Step-by-step explanation:

It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

≥ -4

Step-by-step explanation:

at least means the least  is allowed to be is - 4. and cannot go lower than -4

hope this helps
