Question

HELP ASAP!!! DUE SOON!!!
Linear,exponential, or neither?

Answer 1

It is therefore a exponential function, as y increases with x.

Explanation:

coordinates: ( 7 , 5 ) , ( 16 , 10 )

Slope:
`(y2-y1)/(x2-x1)`

:
`(10-5)/(16-7)`

:
`(5)/(9)`

equation: y - y1 = m( x - x1 )

:
`y - 5 = (5)/(9)(x - 7)`

:
`y = (5)/(9)x+(10)/(9)`

check if third coordinates matches:

`y = (5)/(9)(25)+(10)/(9)`

`y = 15` ......does not match, so its not linear.
