Need help with two geometry questions !!!

1. The vertices of a triangle are A(-6,4), B(-3,5) and C(1,-1). Name the vertices of the image reflected across the x-axis.

2. Find the image of O(-2,-1) after two reflections, first across the line y=-5, and the across the line x=1.

For 1, if you reflect a point or in this case a vertex, across the x-axis, then your x-value remains the same and your y-value changes sign.|dw:1394150629945:dw|
