Hello, I really truly need help please, PLZ! Thanks!

1. Second Choice

2. Positive

3. Line B

4. Line D

5. Horizontal

Step-by-step explanation:

The y-intercept is the value of b —

where m = slope and b = y-intercept.

Looking from the graph, the graph passes y-axis at (0,1) which is y-intercept.

Basically (0,a) is y-intercept.

Thus, our y-intercept is (0,1)

The slope is positive. If the slope is negative, it would face opposite.

For zero slope, the graph will become a horizontal line.

An undefined slope is the vertical line graph.

Line B has zero slope. As said, the zero slope will turn the graph into a horizontal line.

Line D has an undefined slope. Read Third Screenshot.

As said, an undefined slope is the vertical line.

This is called Constant Function where the graph is a horizontal line. For a vertical line, it must be x = a (where a is constant)

FYI,

y = a — horizontal

x = a — vertical

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
