The equation that matches this diagram is
4(z + 1.1) = 20.8 . What is the value of Z.

4.925

Step-by-step explanation:

first you minus 20.8 from 1.1, after that you divide 19.7 by 4 and that's is how you would get 4.925.

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: the answer for that is 22/3
