Question

quadrilateral A'B'C'D' is the image of quadrilateral ABCD after being translated 6 units up and 7 units left. Quadrilateral A prime, B prime,C prime,D prime, where point B has coordinates (negative 3,5) What are the coordinates of the pre-image point B?​

Answer 1

Answer:

$B(x,y) = (-10,-1)$

Step-by-step explanation:

Given

$B' = (-3,5)$

Required

Determine B

When a point is translated up, the result is:

$y'->y + h$

Where h is the unit translated

y' is the new point and y is the previous;

So, we have

$5 = y + 6$

$y = 5 - 6$

$y = -1$

When a point is translated left, the result is:

$x'->x + h$

Where h is the unit translated

x' is the new point and x is the previous;

So, we have

$-3 = x + 7$

$x = -3 - 7$

$x = -10$

Hence, the coordinates of B is

$B(x,y) = (-10,-1)$

Answer 2

the answer is (0,2)
