Question

a triangle has vertices at r(1,1), s(-2,-4), and t(-3,-3). the triangle is transformed according to the rule r_{90^{circ}}. what are the coordinates of s? (-2,4) (-4,2) (2,4) (4,-2)

Explanation:

Step1: Recall 270° rotation rule

For a point (x,y), R₀,270° gives (y,-x)

Step2: Apply to S(-2,-4)

x=-2, y=-4 → (y,-x)=(-4, 2)

Answer:

(-4, 2)
