Answer:
- 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m =
=
= 5
Given a line with slope m then the slope of a line perpendicular to it is
= -
= - 
In this question the main part is to convert the mixed fraction into the decimal form. I hope the procedure i am going to show would be the easiest procedure to solve this kind of problems. Now let us get down to solving the problem in hand.
6 3/4 = 27/4
We have reached the above deduction by multiplying 6 and 4 and then adding 3 with the result. Now we will come down to the decimal part.
27/4 = 6.75
So 6.75 is the decimal form of 6 3/4.
That will be 5000
1km = 1000m sorta like m and cm
5×1000=5000
