Step-by-step explanation:

Transform System A to system B

option c

Transform System B to system C

option b

2x - 4y = -10          A1

-8x + 7y = 22        A2

A1 * 4   > 8x - 16y = - 40

A2        > -8x + 7y = 22       {Add }

                         -9y       = -18      B2

B2 ÷ (-9)      y = 2

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
