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 .

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000

it could be a ..idk tho
