Write the equation of a line perpendicular to 5x−9y=−8 that passes through the point (−5,8).

 y = -(9/5)x - 1

Step-by-step explanation:

Rewrite the equation in standard form:  y = (5/9)x+(8/9).  [y=mx+b]

A line perpendicular to this would have a slope that is the negative inverse of the original slope (5/9), which would make it -(9/5).  The y-intercept would also change, but we don't know the value, yet.  For now, we'll use "b" for the y-intercept.  This results in a perpendicular line:

y = -(9/5)x + b

We can calculate b, the y-intercept, by using the point (-5,8) and solving for b.

8 = -(9/5)*(-5) + b

8 = (9) + b

b = -1

The line perpendicular to 5x−9y=−8 that passes through the point (−5,8) is

y = -(9/5)x - 1

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

hope my answer has you!

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
