Triangle LMN has verticles L(-6,5),M(-4,-3). Find the coordinates of the vertices of its image after it is?

Question

reflected over the X-axis and then translated by (-3,0).

a.L(-9,-5),M(-7,3),N(-2,-4)

b.L(-6,-5),M(-4,-3),N(-2,-4)

c.L(-5,-6),M(-7,3),N(-2,-4)

d.L(9,5),M(-4,-3),N(-5,-4)

Answer 1

Reflecting over the X-axis means to make the positive Y values negative and the negative Y values positive. That yields:

L(-6, -5), M(-4, 3)

Translating by (-3, 0) means adding -3 to the X values. That yields:

L(-9, -5), M(-7, 3)

Those points are only found in answer A, so the answer is A.

Finally, this question is more geometry than geography, and FYI there is a Mathematics category that might be better for questions like this in the future.

Good luck!
