First

In = x

out =y

when x=0 , y=1

so in order to find the rule we have, because the one we have in x=0

y=kx+1

so we need to find k for example using x=2 y=7

7=k(2)+1

Then we isolate the k

2k=7-1

2k=6

k=6/2

k=3

so the rule is

y=3x+1

for x=5

y=3(5)+1=16

x=5 y=16

for y=25

25=3x+1

25-1=3x

24=3x

x=24/3

x=8 y=25

the missing values are

16

8
