The rule as a mapping for the translation of a rectangle is (x, y) → (x – 2, y + 7). which describes this translation?

Translation of 2 units to the left and 7 units up.

Step-by-step explanation:

The general rule of translation is

             .... (1)

If a>0, then figure translate a units right and if a<0, then figure translate a units left.

If b>0, then figure translate b units up and if b<0, then figure translate b units down

The given rule of translation is

            .... (2)

On comparing (1) and (2), we get

a = -2 < 0, so figure translate 2 units left.

b = 7 > 0, so figure translate 7 units up.

Therefore, the given rule describes the translation of 2 units to the left and 7 units up.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
