Step-by-step explanation:

We have two points.  We can find the slope m using

m = (y2-y1)/ (x2-x1)

   = (8--2)/ (1-3)

      (8+2)/(1-3)

     10/-2

   -5

The slope is -5

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total candidates = 23+ 2 + 3 = 28

and, Each canoe can hold 3 people.

So, number of  canoes will they need

= 28/3

= 9.333

Hence, 10 canoes will they need.
