Parallel slope = 2
This is because the original line has slope 2. Parallel lines have equal slopes.
--------------------------
Perpendicular slope = -1/2
The original slope 2 or 2/1 turns into -1/2 after flipping the fraction and the sign. Note the original slope and perpendicular slope multiply to -1. This is true for any pair of perpendicular lines where neither line is vertical.
Answer:
A 7.81
Step-by-step explanation:
Use the distance formula to find the distance between coordinates.

16 over 70 or 8 over 35 to simplify.
First you have to divide the 9 on both sides to get x alone. Next you would have to divide 117 and 9. (117÷9=13) . So x>13
