9) $y = 2x + 5$

10) The y-intercept is always the constant term (without $x$ ). Therefore, the y-int is -9. The slope is always the term in front of the $x$ , and so it is 3.

Answer:

The additional 1.3% of increase in the annual interest rate that Jack is receiving in his savings account, from 2.8% to 4.1%, represent an increase of 46.42%.

Step-by-step explanation:

Jacks's savings account annual interest rate before = 2.8%

Jacks's savings account annual interest rate after the increase = 4.1%

Difference of the two rates = 4.1% - 2.8% = 1.3%

How much percentage is that additional 1.3% from the rate before the increase?

(1.3 * 100)/ 2.8 = 130/2.8 = 46.42%

The annual interest rate increased by 46.42% from the previous annual interest rate.
