Answer:

Step-by-step explanation:
Given
Equation: 
Required
Determine the equation of Point: (5,4)
First, we need to determine the slope of 
The general form of an equation is 
Where m represents the slope;
Hence; 
Since the equation and the point are parallel. then they have the same slope (m).

Next, is to determine the equation of the point, using the following formula:

Where

So, the equation becomes

Cross Multiply

Open Bracket

Make y the subject of formula


Hence, the equation is 
To get it in its simplest for you have to find a number high enough to go into both. The highest number which goes into both is 9.
So the answer is 2/9 because you divide them both by 9
Answer:
192m³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a square based pyramid
The highlighted figure is a square based pyramid
The volume of a pyramid is
V=a²h/3
Where a= base length
h= height
Given a= 8m
h= 9m
Volume = 8²*9/3
Volume = 64*3
Volume = 192m³
