Question

A figure is transformed according to the rule (x,y) = (x-1, y + 4). What transformation has taken place?

A. Translation of each point 1 unit to the left and 4 units up.

B. Translation of each point 1 unit to the right and 4 units up.

C. Dilation by a scale factor of -1/4.

D. Reflection over the x-axis, then translated up 4 units.​

Answer 1

The figure has undergone a translation of each point 1 unit to the left and 4 units up.

Step-by-step explanation:

The transformation that has taken place is a translation of each point 1 unit to the left and 4 units up. This means that every point in the figure has been moved to the left by 1 unit and up by 4 units.

Answer 2

The answer is A because x-1 means moving left 1 on the x axis. As well, y+4 means moving 4 up on the y axis.
