With a Amsler grid one can determine if one has distortion in ones visual field. Distortion means that objects alter shape. A Amsler grid is a square which is devided into many smaller squares and a dot in the middle. From the dot there are lines going out to the corners of the big square.
Well, honey, you just shade in 30 squares on that 100 grid. Each square represents one hundredth, so get to coloring and make sure you stay in the lines. It's as simple as that, darling.
One column in a hundredths grid has 10/100's in it One column in a tenths grid has 1/10 in it. You can tell that 10/100=1/10 by looking at the two visuals.
There cannot be a sensible answer because the proposition is false.
Two lines are coplanar if they both have 2 points in the same plane. So in an X,Y,Z grid, one slope, be it X Y or Z, must be the same for both lines. To find the slope, use Y1-Y2/X1-X2 or replace one of those values with Z. For this particular example, it doesn't matter which is on the numerator, because it is a comparison. ================================ Short-cut: Two lines that intersect are always coplanar.
