How is the graph of y = (x-1)2- 3 transformed to produce the graph of Y= = 3(x+4)??
1
The graph is translated left 5 units, compressed vertically by a factor of 2, and translated up 3 units.
The graph is stretched vertically by a factor of ạ, translated left 5 units, and translated up 3 units.

The graph is translated left 5 units, compressed horizontally by a factor of 2, and translated down 3 units.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

step-by-step 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.
