PLEASE HELP ME I'M DESPERATE :( Perform the following series of rigid transformations on ∆ABC:

Translate ∆ABC by moving it 5 units to the right and 2 units up.
Draw the line y = -x, and reflect ∆A'B'C' across the line.
Rotate ∆A''B''C'' counterclockwise about the origin by 270°.

Show each transfromation - There should be three triangles and the line of reflection

step-by-step explanation:

use that smart brain

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer: 7
