Question

A.

J' (10, 25), K' (60, 25), L' (50, 0), M' (0, 0)

B.

J' (10, 5), K' (60, 5), L' (50, 0), M' (0, 0)

C.

J' (7, 10), K' (17, 10), L' (15, 5), M' (5, 5)

D.

J' (2, 25), K' (60, 5), L' (50, 0), M' (0, 0)

Answer 1

help me guys

Answer 2

I have to go, but I'll tell you what you need to do.

Answer 3

Look at the given point J(2, 5).

Choice A.
Now look at point J'(10, 25)

What do you do to 2 to end up with 10 and what do you do to 5 to end up with 25?

Answer 4

you multiply

Answer 5

by what?

Answer 6

2x5 and 5x25

Answer 7

I mean not 5x25 5x5

Answer 8

Correct.
A dilation from the origin must have every new x-coordinate and every new y-coordinate always always be obtained by multiplying the original coordinates by the same number.
Since for point J, the multiplier is 5, check the other points of choice A. If every x-coordinate and every y-coordinate was also multiplied by 5, that is the answer.

If not, look at the next choice. The multiplier does not have to be 5. It just has to always be the same number.

Sorry, but gtg.
