But it is possible that two x-values have a single y value
So let us make a selection from the table
We have the correct option as;
W
A,b are 8,2. its an easy guess.
now that makes it easy
(b-y)(a-x)
Step-by-step explanation:
<u>The correct question is;</u>
Grouping method to factor the given expression: ab-ay-bx+ xy
