The x intersect is at 2,5 and the y intersect is at -1,5
2,5 + (-1,5) = 1
The answer should be the first option.
The first option says that the sum of x + y = more or the equal than 1.
Hope it helped!

Answer:
v= 6km/h - 1km/h^2 * t
Step-by-step explanation:
From the information, it seems the runner is slowing down because the speed at 1st hour is 5km/h but at 3rd hour becomes 3km/h.
If v= velocity, v0= initial speed, t= time, and the a=acceleration then the function would be:
v= v0 + a * t
To find the acceleration you need to do this equation:
acceleration= velocity1- velocity3 / t3-t1
a = (3km/h-5km/h)/ (3 hour- 1 hour)
a = (-2km/h)/2hour= -1 km/hour^2
After that, you need to find the initial speed. Try to put the 1st-hour variable into the full equation. It would look like this
v= v0 + a * t
5km/h= v0 + (-1 km/hour^2 * 1 hour)
v0= 5km/h + 1km/h
v0= 6km/h
Then the full function would be:
v= 6km/h - 1km/h^2 * t
The graph would look like a backslash(\) from 5 gradually go down to 1.

I would say A because every other question it shows the exact amount but since it says 20-29 you can’t really say the answer by looking at the graph unless you guess but that’s not what the question is saying it’s saying which question cannot be answered by looking at the graph and I would Say You cannot answer A by looking at the graph.
Sorry if I am wrong
