The given point ( 1 , -3) is reflected over the y-axis.

9514 1404 393

  (-1, -3)

Step-by-step explanation:

Reflection over the y-axis negates the x-coordinate:

  (x, y) ⇒ (-x, y) . . . . reflection over the y-axis

  (1, -3) ⇒ (-1, -3) . . . . reflected point

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
