The y-coordinate of point C may have a value of 5 or -1.
<h3>What is a right-angle triangle?</h3>
If any of its inner angles is 90 degrees, the triangle is said to be right-angled. Another term for this triangle is the right triangle or 90-degree triangle.
The given data in the problem is;
A coordinate plane contains the right triangle ABC.
AB = 6 units
Surface area, A= 9 square units
The AB symbol is located on the x-axis parallel line y=2.AB will thus be perpendicular to the x-axis.
As a result, AB will be parallel to the side that contains point C. (BC or AC). As a result, the triangle's area should be justified by the length of the side or leg containing point C, which is the point's y-coordinate.
The other triangle leg's length should be,
BC = AC = 9/3
BC = AC = 3
Therefore, the point C's y-coordinate can be,
2±3 = 5,-1
Hence, the y-coordinate of point C may have a value of 5 or -1.
