3y=x-3
y=1/3x-1
Perpendicular slope: -3
y=-3x+b
Plug in the coordinates in the equation:
-9=-3(5)+b
-9=-15+b
4=b
Equation: y=-3x+4
Also, when finding the perpendicular slope you take the reciprocal of the original slope and make it negative if it is positive and make it positive if it’s negative.
Answer:
B
Step-by-step explanation:
notice the first term is -10, and the common difference is 3, so we add 3 to get the next term.

check the picture below.
B because absolute value means the distance of a point on a number line from 0. So the absolute value of -6 is 6 and you add that to 4
