Question

Give the rule for translating a point 4 units left and 8 units up

Answer 1

Answer:

(x-4,y+8)

Step-by-step explanation:

Given

$Point = (x,y)$

Required

Translate

• 4 units left
• 8 units up

8 units up

The general rule for up translation is;

$f'(x,y) = f(x,y+h)$

Where h is the unit translated up

In this case:

$h = 8$

So, we have:

$f'(x,y) = f(x,y+8)$

4 units left

The general rule for up translation is;

$f'(x,y) = f(x-b,y)$

Where b is the unit translated left

In this case:

$b = 4$

So, we have:

$f"(x,y) = f(x -4,y+8)$

Hence, the rule of translation is: (x-4,y+8)
