Answer:

Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to

Step 1
Find the slope m
Let


Step 2
Find the value of b
we have


substitute in the equation of the line



The equation in slope intercept form is equal to

i. 171
ii. 162
iii. 297
Solution,
n(U)= 630
n(I)= 333
n(T)= 168
i. Let n(I intersection T ) be X

<h3>ii.
n(only I)= n(I) - n(I intersection T)</h3><h3>
= 333 - 171</h3><h3>
= 162</h3>
<h3>
iii. n ( only T)= n( T) - n( I intersection T)</h3><h3>
= 468 - 171</h3><h3>
= 297</h3>
