Linear because x moves up by 3 and y moves up by 7
Not entirely, it could be an isoceles triangle (a triangle which all sides are different lengths) but there is still a possibility.
Given:
The coordinates of point K' are (6,5).
K' is the image of K after a reflection in the line y=2.
To find:
The coordinates of point K.
Solution:
Let the coordinates of point K are (a,b).
If a figure is reflected over the line y=2, then
Using this formula, the coordinates of image of K are

The coordinates of point K' are (6,5).

On comparing both sides, we get




Therefore, the coordinates of point K are (6,-1).
-22 = - (x - 4)
= -22 = -x + 4 (distribute the minus)
= -26 = -x (subtract 4 from both sides)
= 26 = x (divide by -1 to remove the minus from x)
so, x = 26
Answer:
t=-3
because if you multiply -7 by 3 and then subtract, you will get 20
