Analyze the graph below and complete the instructions that follow. https://media.education2020.com/evresources/2089856_a369f2f5-707b-4b0d-866c-dfe7440fb37e.png The coordinates of the vertices of https://media.education2020.com/evresources/2089856_225128ba-be85-4320-bb63-c0b104cb23ed.png are G(–2, 3), H(–1, 2), and I(–3, 1). If https://media.education2020.com/evresources/2089856_d7e86004-4310-4145-befc-21f018b74f31.png is reflected across the x-axis to create https://media.education2020.com/evresources/2089856_28781760-f009-4b9e-99f0-760b1422ca28.png find the coordinates of the vertex located at point W. A. (–2, –3) B. (–2, 3) C. (2, –3) D. (3, 2)

Hello! If I understand your question, it asks you to find the coordinates of a point W if reflected across the x axis. Correct?

OpenStudy (eboogie4):

Yeah

OpenStudy (noseboy908):

Ok, so this should be somewhat simple. Tell me this: If I reflect any ordered pair across the x axis, what changes?

OpenStudy (eboogie4):

@noseboy908 Hey dude can u finish helping me sorry I left

OpenStudy (eboogie4):

think it is B

OpenStudy (eboogie4):

@Dani_Rose @Daniee_Bruhh

OpenStudy (noseboy908):

Unfortunately you're incorrect. When an ordered pair is reflected across the x axis, you leave the x value alone, and add a negative to the y value. Outcome?

OpenStudy (eboogie4):

The Y is negative?

OpenStudy (noseboy908):

The y value becomes negative, yes. What does that do to your point of (-2,3)?

OpenStudy (eboogie4):

(-2,-3)? Cause you said leave the x alone

OpenStudy (noseboy908):

Correct! There's your answer.

OpenStudy (noseboy908):

If, for example, the question asked you to reflect across the y axis, you'd leave the y value alone and make the x value negative.

OpenStudy (eboogie4):

Thx can u help with more

OpenStudy (noseboy908):

Sure.
