Then in step 4 I plug in every Y and X given in the table.
Results ;
X = 4 X = 0 Y = 6 Y = 3
B is the correct answer !
If you have any questions, please leave a comment (:
( P.S ignore the first 3 step on the very top, the one that starts with "y-2 = 1/4 (x+8)" that equation is wrong. The first bottom 3 steps are the correct ones)
I would draw the triangle then it would be easier to answer. It is not an equilateral because it is not equal on all sides. Perhaps scalene because all the sides are not the same.
