Aloiza [94]

Answer:

• Formular for length:

length =  \sqrt{ {(x _{1}  - x  _{2}) }^{2}  +  {(y_{1} - y_{2})}^{2} }

• from points given, x1 is -5, x2 is -5, y1 is -3 and y2 is -6:

• substitute:

length =  \sqrt{ { \{ - 5 - ( - 5) \}}^{2}  +  { \{ - 3 - ( - 6) \}}^{2} }  \\  \\ length =  \sqrt{ {0}^{2} +  {3}^{2}  }  \\  \\ length =  \sqrt{ {3}^{2} }  \\  \\ { \boxed{ \boxed{ \:  \: length = 3 \: units \:  \: }}}

frez [133]

Answer:

The answer is "\bold{(x,y)\longrightarrow (x-8, y-7)}".

Step-by-step explanation:

In the given question some data is missing. so, the correct answer to this can be explained in the following example:

In the given example, point D  is also known as the coordinates in the (2, 5), and in the coordination of the D prime (D') and after translation its co-ordinates value is (-6, -2). Since the very first choice is only accurate as:

⇒2-8 = -6

⇒ 5-7 = -2

It can try certain things too and see why this alone is the correct translation.
