Multiple chice! 1.) equations can be translated because they are sets of points they are on located on graphs they have distinct values they include operators 2.) a translated equation should be equivalent to the original equation except for variables referring to a given point variables referring to x or y operators should be reversed none of the above

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
