Question

Identify the algebraic description that maps a point (3, 7) onto another point (-5, 7).

Answer 1

Answer:

A) (x, y) → (x - 8, y)

Step-by-step explanation:

(3, 7) →  (-5, 7)

Without adding or subtracting any values, we can immediately tell that the y-value did not change, but the x-value did. With this, we are left with choices A and D.

A) (x, y) → (x - 8, y)

   (3, 7) → (3 - 8, y)

   (3, 7) → (-5, 7)

This matches our problem, and therefore, A is the correct answer.

Hope this helps!
