Consider the following.

(-8, 7); x + y = 13 → y= -x + 13

parallel lines have the same slope. slope is -1

y = -x + b

7 = -(-8) + b

7 = 8 + b

b = -1

(a) y = -x - 1

perpendicular lines have opposite slopes. slope is 1/2.

y = -1/2x + b

7 = -1/2(-8) + b

7 = 4 + b

b = 3

(b) y = -1/2x + 3

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
