As per an axiom in euclidean geometry, if points lie in a plane, the containing those points also lies in the same plane.

is TWO, LINE

example: If two points lie on the same plane, then the line containing them lies on the same plane. Think of two distinct points on a normal Cartesian coordinate grid. If both points are on the grid, then a line can be drawn between them on the same grid. In this case, the grid itself is the 2-dimensional plane.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
