Answer:
First option
Step-by-step explanation:
There is a mistake in the description of the first function.
On a coordinate plane, a straight line with a positive slope crosses the x-axis at (-6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (-4, 1), (0, 3).
Given two points of a function, (x1, y1) and (x2, y2), its rate of change between them is:
Rate of change: (y2 - y1)/(x2 - x1)
Points of the 1st graph: (-4, 1), (0, 3).
Rate of change: (3- 1)/(0 - (-4)) = 1/2
Points of the 2nd graph: (-4, 1), (0, -3).
Rate of change: (-3 - 1)/(0 - (-4)) = -1
Points of the 3rd graph: (-4, 0), (0, 4).
Rate of change: (4 - 0)/(0 - (-4)) = 1
Points of the 4th graph: (-4, 0.25), (0, 4).
Rate of change: (4 - 0.25)/(0 - (-4)) = 0.9375
