Answer: It is a right triangle.
the attachment shows the graphed triangle.
Step-by-step explanation: The slope of the line between coordinates (-2,-3) and (2,1) is +1 rise/run is 4/4
The slope of the line between points (2,1) and (5,-2) is -1 rise/run -3/3
These slopes are perpendicular to each other, so they form the right angle of this triangle.
