PLEASE HELP WILL MARK BRAINLIEST!!

A point in Quadrant III is reflected across the y-axis. What is true about the new location? Check all that apply.

The new location is in Quadrant II.
The new location is in Quadrant IV.
The new location has a positive x-coordinate and a negative y-coordinate.
The new location has a negative x-coordinate and a positive y-coordinate.
The new location has negative x- and y-coordinates.

The answers are:

-The new location is in Quadrant IV

-The new location has a positive x-coordinate and a negative y-coordinate

Step-by-step explanation:

I'm not sure how you can explain this but if you go to desmos, it's an app for graphing, graph a random point on Quadrant lll, flip it over the y-axis, and you will see it landed on quadrant IV (Quadrant 4, the positive x-axis and negative y-axis.)

Sorry if this is confusing, feel free to ask if you have any questions.

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.
