Which shows the image of δrst after the rotation (x, y) → (y, –x)? image a, b, c, d? (tap image above)

Consider triangle RST. It has vertices R(-2,1), S(1,3) and T(-1,7).

If the rotation has rule

(x, y) → (y, –x),

then

R', S' and T' are exactly vertices of triangle from the first diagram.

correct choice is A.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
