Given:

Point A with coordinates: (4, 2) is in the first quadrant.

The point is translated to the rule (x, y) --> (x+1, y-5)

Now, point A becomes (4+1, 2-5) = (5, -3) which is now in quadrant 4. 

The point is reflected across the y-axis. Now, it is in the third quadrant.

The line AB has midpoint (2,5).<br> A has coordinates (1, 2).<br> Find the coordinates of B.
Gekata [30.6K]

Answer:

X_m = \frac{A_x +B_x}{2}= \frac{1+B_x}{2}= 2

And we can solve for B_x and we got:

1+B_x = 4

B_x = 3

Y_m = \frac{A_y +B_y}{2}= \frac{2+B_y}{2}= 5

And we can solve for B_x and we got:

2+B_y = 10

B_y = 8

So then the coordinates for B are (3,8)

Step-by-step explanation:

For this case we know that the midpoint for the segment AB is (2,5)

And we know that the coordinates of A are (1,2)

We know that for a given segment the formulas in order to find the midpoint are given by:

X_m = \frac{A_x +B_x}{2}= \frac{1+B_x}{2}= 2

And we can solve for B_x and we got:

1+B_x = 4

B_x = 3

Y_m = \frac{A_y +B_y}{2}= \frac{2+B_y}{2}= 5

And we can solve for B_x and we got:

2+B_y = 10

B_y = 8

So then the coordinates for B are (3,8)
