Can someone please help me I don’t understand this. I keep getting it wrong

Answer:

K- (-8, -2)

L- (2, -2)

J- (-8, -5)

M- (2, -5)

Step-by-step explanation:

Vertices refer to the points where the lines connect, or corners. In this problem they're represented by K, L, J, and M.

The current coordinates are-

K- (-8, -4)

L- (2, -4)

J- (-8, -7)

M- (2, -7)

Since the Y coordinate refers to vertical distance and the X coordinate refers to horizontal distance, translating them two units up would involve adding positive two to each y coordinate.

Therefore the new coordinates would be

K- (-8, -2)

L- (2, -2)

J- (-8, -5)

M- (2, -5)

Hope this was helpful! Sorry if I messed up askdjasjk
