Answer:
Slope is m=0
Step-by-step explanation:
The slope of any line that is perpendicular to the y-axis is zero.
The reason is that any line that is perpendicular to the y-axis is also parallel to the x-axis and the slope of the x-axis is zero.
The equation of any line perpendicular to the y-axis is and passes through (a,b) is y=b.
The given point is (-5,-3) hence the required equation is
We have been given that in an account an amount of 7,650 is invested at 9.15 percent compounded quarterly for 8 years and 6 months.
We will use compound interest formula to find our answer.
,
Where, P= principle amount, A= amount after T years, n= period of compounding and r = interest rate (decimal).
Let us substitute our given values in our formula.
Therefore, after 8 years and 6 months our amount will be 16505.497.
