coordinate geometry

Let S₁ be the plane figure consisting of the points (x, y) given by the inequalities |x - 1| ≤ 2 and |y + 2| ≤ 3. Let S₂ be the plane figure given by the inequalities x - y ≥ -2, y...

A robot arm $$PQ$$ with end coordinates $$P(0,0)$$ and $$Q(2,5)$$ rotates counter clockwise about $$P$$ in the $$XY$$ plane by $${90^ \circ }$$. The new coordinate pair of the end...
