The missing graph is attached with the answer.
<h3>What is a Linear Function ?</h3>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.
