we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

Step 1
<u>Find the slope of the given line</u>
we have

Solve for y
Divide by  both sides
 both sides


the slope of the given line is 
Step 2
<u>Find the slope  of a line that is perpendicular to the given line</u>
we have
 


substitute the value of m1

therefore
<u>the answer is</u>
the slope is 
 
        
             
        
        
        
Answer:
Step-by-step explanation:

Answer:
Substitute the 80°F where the F is in the equation. then just put the whole equation into your calculator. I got approximately 26.7.
 
        
             
        
        
        
4/5 x 2= 8/5
Which is 1 3/5 cups needed for 2 pies
