7% of $5100 is 357
416.50 / 357 = 1.16
I will take 1.16 years to gain $416.50
Since .68 is 68/100, you can simplify to 17/25.
Y-3=4/11(x-11). Doing a problem like this is mostly memorizing point slope formula, by knowing y-y2=m(x-x1) you can just "plug" in 3 as your y1 and 11 as your x1 then finally 4/11 as your slope being y-3=4/11(x-11)
(15,-10) (17,2)
(2+10)/(17-15)= 12/2 = 6
The slope is 6
