Okay, the question is - "triangle sign"GHI with vertices G(-1,3), H(-4,2), and I(-2,4) reflected over the x-axis.

a reflection in the x axis means you leave the x axis as is and you negate the y value, for example, (x,y) would become (x,-y)
so according to that your points would be as follows:
g(-1,3)-->g'(-1,-3)
h(-4,2)--->h'(-4,-2)
i(-2,4)----i'(-2,-4)
now just graph!!
hope that helps!!

A reflection is a mirror image of your original figure. Your triangle is originally in Quadrant 2 since the x values are negative and the ys are positive. If you are reflecting over the x-axis, you will end up in Quadrant 3. Multiply your y coordinates by negative 1 and keep the same x coordinate. So G'(-1,-3),H'(-4,-2), and I'(-2,-4) are the coordinates of the reflected triangle. The image triangle is labeled G'H'I'.

to reflect a pointover x-axis, you count how many boxes away from the x-axis it is, then count that many on the other side (with same y-value) and put a point.
so it would be(-1,3)becomes(-1,-3)
(-4,2) becomes (-4,-2)
(-2,4) becomes (-2,-4)
