In your own words, how do you solve a two-step equation? How do you test if your solution is correct? Use academic vocabulary such as inverse, isolate,
substitute, etc., in your explanation,

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.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know
