HELP ASAP GIVING BRANLIST 100 POINTS!!

Answer 1

see below

Explanation:

We use the slope formula

m= (y2-y1)/(x2-x1) for x=3 and x=1

= (33-20) / (3-1)

=13/2

m= (y2-y1)/(x2-x1) for x=5 and x=3

= (48-33) / (5-3)

=15/2

The average rates are not the same

The change from 3 to 5 is higher

Answer 2

Rate of change = difference in y over difference in x.

Rate of change = (33-20)/(3-1) = 13/2

Rate of change = (48-33) /(5-3) = 15/2

The rates are not the same so it isn’t linear.

The rate of change for x=3 and x = 5 is greater.
