Question

Help please thank you

Answer 1

9 is but 10 is not

Explanation:

for 9 it's 0,0 92,2 184,4 etc.

for 10 there is no pattern

Answer 2

See below

Explanation:

Problem 9:

Yes it is proportional because the vehicle is moving at a constant speed of 41 mph (as 92/2=41). So if you don't drive, your speed is 0 mph which is accurate in regards to the graph.

Problem 10:

No it is not because due to the y-intercept not being 0, y doesn't vary directly with x. However, the slope remains constant, but it's not the same thing as proportional
