    The coordinates of point P on a coordinate grid are (−5, −6). Point P is reflected across the y-axis to obtain point Q and across the x-axis to obtain point R. What are the coordinates of points Q and R? Q(5, 6) and R(−5, −6) Q(−5, −6) and R(5, 6) Q(−5, 6) and R(5, −6) Q(5, −6) and R(−5, 6)

    For unit conversion: See this video: https://www.khanacademy.org/math/pre-algebra/rates-and-ratios/metric-system-tutorial/v/unit-conversion As for finding the distance between points you just use Pythagorean theorem \[( (x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2 )^{\frac{1}{2}} = distance\] see: http://www.purplemath.com/modules/distform.htm For the last problem you posted I recommend graphing the point, also by reflected it means that if you were to fold the graph paper in half along the y axis both points would be overlapping for example: |dw:1438134584455:dw|

    I made a mistake in the graph, as far as the coordinates If you were reflect the point (2,1) about the y axis you would get point (-2,1) |dw:1438134703836:dw|

    As you see if you folded the graph in half about the y axis both (-2,1) and (2,1) would be overlaping

    look at my example or watch this video: https://www.khanacademy.org/math/basic-geo/basic-geo-coordinate-plane/copy-of-cc-6th-coordinate-plane/v/reflecting-points-exercise
