    Exclamation [SOLVED] Triangle Transformation

    I'm not too sure how to explain this but this is what the question says:
    Draw the image of (triangle) EFG after the transformation, identify the type of transformation.

    Now I'm not going to show the triangle because I have gotten a warning because people thought I wanted my homework done for me, but I'm simply going to ask what these mean.

    (x,y) -> (x+2,y-3) Does this mean for every point on the triangle that is on the x I add two and for every on the y I subtract 3?

    (x,y) -> (-x,y) ... What...?

    (x,y) -> (x,-y) ...^ same deal as above.

    The last one was done as a demo in class while I was confused, so I have that one done. Help?

    yes, so if say (1,1) is a vertex of the triangle, it would become (3,-2)

    (x,y) -> (-x,y) ... What...?
    this is a reflection in the y-axis. the point (1,1) would become (-1,1)

    (x,y) -> (x,-y) ...^ same deal as above.
    similar to above. this is a reflection in the x-axis
