Question

some of the choices are incorrect so be careful...
the graph has a
the line is going because the elevation is slowly as time goes by
the hiker started at an elevation of feet.
it takes the hiker minutes to reach the ground safely.
true or false: the point (12, 120) is part of the graph
true or false: the point (8, 220) is part of the graph
the is not part of the graph because the line doesnt start at ground level.
false; positive; ascending; 18; 360; true; negative; upwards; origin; downwards; descending; 400; 20

Explanation:

Step1: Determine slope

The line is going downwards, so slope is negative.

Step2: Analyze line direction

The line is going downwards as elevation is decreasing.

Step3: Find starting elevation

The line starts at 400 feet on y - axis.

Step4: Find time to reach ground

It takes 20 minutes to reach y = 0.

Step5: Check point (12, 120)

False, not on the line.

Step6: Check point (8, 220)

False, not on the line.

Step7: Identify non - part of graph

The origin (0,0) is not part as line doesn't start at ground level.

Answer:

negative; downwards; descending; 400; 20; False; False; origin
