Question

the slope is zero, and angels temperature is the same every day. if the slope was a different number, then it would mean his temperature was going up or going down.
the slope is undefined, and angels temperature is the same every day. if the slope was different, then it would mean that he was sick with a fever
the slope is undefined, and angels temperature is the same every day. if the slope was different, then it would mean his temperature was going up or going down.
the slope is zero, and angels temperature cannot be determined since this is not a function. if the slope was a different number, then it would mean that he was sick with a fever

Explanation:

The graph shows a horizontal line (temperature vs. days). A horizontal line has a slope of 0, which means the y-value (temperature) is constant. A non-zero slope would indicate the temperature is increasing or decreasing.

Answer:

The slope is zero, and Angela's temperature is the same every day. If the slope was a different number, then it would mean his temperature was going up or going down.
