The missing graph is attached with the answer.

What is a Linear Function ?

A linear function is a function that can be represented by the formula y = mx+c ,

m is the slope of the equation , c is the intercept at y axis.

The student will have 130 dollars in the bank at the end of week 11.

For each passing week, the student will have $10 more in the bank than at the end of the previous week. So, following this pattern:

At 4 week $50

At 5 week $60

The slope =

m =( 60-50)/1 = 10

y = 10x +c

at x = 0 , y = 20

c = 20

The equation is

y = 10x +20

y = 110 +20

y = $130

At the end of 11 weeks, he will have $130.

The student will have 130 dollars in the bank at the end of week 11.
