Answer:
Step-by-step explanation:
At x=0, y=0
Then, y=kx+h
0=k×0+h
Then, 0=0+h
h=0
This shows that the line pass through the origin and has no intercept
Then the equation becomes
y=kx
So we can pick any of the point to get k
At y=142, x=4.5.
142=4.5k
k=31.55556
To the nearest tenths
k=35.6
I hope this help
