Answer:
3½ cups
Explanation:
There are four cups in a US quart. Four cups - ½ cup = 3½ cups.
Given:
End points a line segment are (9,-8) and (-1,-4).
To find:
The equation of perpendicular bisector of given line.
Solution:
Slope of given line is





Product of slopes of two perpendicular line is -1.



So, slope of perpendicular bisector is
.
Perpendicular bisector passes through the midpoint of given endpoints.




So, perpendicular bisector passes through (4,-6) and having slope
. The equation of perpendicular bisector is

where, m is slope.





Therefore, the equation of perpendicular bisector is
.
