Question

the graph shows a plane .
the line is slanting and therefore has a slope.
it takes the plane minutes to touch the ground.
the plane starts at kilometers in the sky.
the graph touch the origin (0, 0).
options: downwards, 15, ascending, does, upwards, positive, does not, negative, descending, 16, 3, 3.5

Explanation:

1. For "The graph shows a plane ______": A plane descending (coming down) makes sense as it's about to touch the ground, so "descending".
2. "The line is slanting ____ and therefore has a ____ slope": Slanting downwards means negative slope (since as x increases, y decreases), so "downwards" and "negative".
3. "It takes the plane ______ minutes to touch the ground": From the options, 15 (or other time, but likely 15 from context) – assuming typical descent time, 15 minutes.
4. "The plane starts at ______ kilometers in the sky": 3.5 (or 3, but 3.5 is an option) – initial altitude, 3.5 km.
5. "The graph ______ touch the origin (0, 0)": Since it starts at some altitude and takes time, it does not touch (0,0) as (0,0) would be ground at time 0, but it starts at altitude, so "does not".

Answer:

1. The graph shows a plane $\boldsymbol{\text{descending}}$.
2. The line is slanting $\boldsymbol{\text{downwards}}$ and therefore has a $\boldsymbol{\text{negative}}$ slope.
3. It takes the plane $\boldsymbol{15}$ minutes to touch the ground.
4. The plane starts at $\boldsymbol{3.5}$ kilometers in the sky.
5. The graph $\boldsymbol{\text{does not}}$ touch the origin $(0, 0)$.
