Pleaseee if you know this can you please answer I’m struggling really bad

⊥ ; ⊥ ; ║

Step-by-step explanation:

( , )

( , )

m =

y = mx + b

"m" is slope

"b" is y-intercept (coordinates are (0, b)

Parallel lines have the same slopes and different y-intercepts.

Slopes of perpendicular lines are opposite reciprocals: × = - 1

~~~~~~~~~~~~~~~~~~~~~~

:  y = x + 5 , = 1 , b = 5

: y = - x + 7 , = - 1 , b = 7

⊥

: = 1 , b = - 2

║ and ⊥  

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
