Question

Write an equation for the vertical translation y=-2/9 |x| -7; 1 units down

Answer 1

y = -2/9 |X| - 8

Explanation:

I'm not certain whether the -7 is part of the |X| or it's just out of the equation. But shifting an equation up or down is very intuitive.

If you want to move an equation up a certain unit, you just add that many units (positive) onto the end of an equation. The same goes for moving a unit down, where you subtract that many units you want to go down.

Answer 2

y=-2/9 |x| -8

Explanation:

y = f(x) + C C < 0 moves it down

y=-2/9 |x| -7 Shift down 1 by subtracting 1

y=-2/9 |x| -7-1

y=-2/9 |x| -8
