Triangle abc is translated according to the rule (x, y) - (x + 2, y-8). if the coordinates of the pre-image of point b are
(4,-5), what are the coordinates of b'?
(2,3)
(1,-9)
(-3,-4)
(6.-13)

6,-13

Step-by-step explanation:

(4.-5)

4-2=6

-5-8=-13

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

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.
