Answer:
yes; AB ⊥ BC
Step-by-step explanation:
If the triangle is to be a right triangle, the slopes of two sides must be opposite reciprocals. The slope is the ratio of rise to run.
mAB = rise/run = -3/4
mBC = rise/run = 4/3
These slopes, -3/4 and 4/3 are opposite reciprocals (their product is -1), so ...
AB ⊥ BC . . . the triangle is a right triangle
