A=16cm/2*5cm
A=8cm*5cm
A=40cm^2
The slope-intercept form: y = mx + b
m - a slope
b - a y-intercept
y = x + 3
Answer: the slope m = 1, y-intercept b = 3 -> (0; 3).
Using given information we have to fill the blank spaces for respective parts:
<u>Part(A): Original ratio of saved to total money per paycheck </u>
Answer: 
Explanation: Original payment was 200 and saving amount is 1 tenth which is 200*(1/10)=20. Hence ratio is 20/200
<u>Part(B): Final ratio of saved to total money per </u>paycheck___________________
Answer: 
Explanation: He also saved money more than 200 represented by x so the new ratio becomes (x+20)/(x+200)
<u>Part(C): Final amount saved per </u>paycheck______________________________
Answer: x+20
Explanation: Final saving is just 20 and extra money over 200 so final saving is (x+20).
Because it would be easier to follow the formula that you were given to solve.
