Okay so all of them pls if two people want to split them then that's good just make sure you check which ones were answered if two people split it up! But if someone wants answer all of them then that's cool too!!! Thanks

answer: its because of life

step-by-step explanation: i dont know

if you was gonna solve for a, a is a   < -12

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
