Answer 1

Do you know how to find the slope of this line?

Answer 2

Ok honey...at the point (0,234), that means that when she started the account, she started it with $234. Then after 5 years she has 270.27, which is the point (5,270.27) See that so far?

Answer 3

Yes.

Answer 4

Ok, you have a linear situation with her account. It grows at a steady rate. So the interest rate can be found by finding the slope of the line between any two points on that line. @Venny is correct here.

Answer 5

yay, finally some normal stuff~!

Answer 6

You use the points on the line to find the rate of change between the points, which in this case is the slope.

Answer 7

\[\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]\[\frac{ 270.27-234 }{5-0 }=\frac{ 36.27 }{ 5 }=7.25\approx7.3\]
