The perpendicular line will have a slope of b/a.
To find this, we first have to solve our equation for slope intercept form.
ax + by = c ----> subtract ax
by = -ax + c ----> divide by b
y = -a/bx + c/b.
So we know the slope of this equation to be -a/b. Since perpendicular lines have opposite and reciprocal slopes, we know we can simply flip the fraction and make it a negative to get the new slope of b/a.

Answer:
9 hours and 45 mins
Step-by-step explanation:
First, this is in army time. (Just so you know!) Also, it goes to 24 hours.
What you would do is add 45 mins to get to a single hour: so 20:15 + 45 = 21:00, then add 3 to get to 24:00 or 12:00 am, then add 6 more hours to get to 6:00 hours. So the final answer is 9 hours and 45 mins
 
        
             
        
        
        
Option A:
The length of diagonal JL is  .
