Solve problems about dilations and write about solution methods. On a coordinate plane, point B is at (1, negative 1). Point B has coordinate B(1, –1). What is the coordinate of B' under a scale factor of 3? (1, –1) (3, –3) (–2, 2) (–6, 6)

B' = (3, -3)

Step-by-step explanation:

If the coordinate (a,b) is dilated by a factor of k, the resulting coordinate will be ()ka, ka)

Given the coordinate (1, -1). When dilated by a factor of 3, the resulting coordinate will be;

B' = 3B

B' = 3(1, -1)

B' = (3(1), 3(-1))

B' = (3, -3)

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

! < 3

have a splendid day < 3 : )

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
