A quarter is either:
A. 1/4
B. 25 cents
if it is 1/4 then
9 quartrers is 9 times 1/4=9/4=2 and 1/4
if it is 25 cents then
0.25 dollars times 9=$2.25
Important: If you're discussing squares, please express "the square of x" as x^2 (not as x2).
Please note that your y=x^2+3 is NOT a line. I will assume (probably incorrectly!) that you meant y=2x+3. The slope of this line is 2, so the slope of any line perpendicular to y=2x+3 is -1/2.
Now use the point-slope equation of a straight line:
y-8 = (-1/2)(x-1) (answer)
