We can use the points (-2, -5) and (18, -5) to solve.
Slope formula: y2-y1/x2-x1
= -5-(-5)/18-(-2)
= 0/20
= 0
Best of Luck!

Answer:
Step-by-step explanation:
Given numbers : 2 , 6, 18, 54
Since common ration between numbers,
So the numbers are in GP.
Now Sum of the numbers = 2 + 6 + 18 + 54 = 80
AM, arithmetic mean between first and last number :
All the conditions are true.
Answer:
1 / X² -4 = (- 1/4) / (X+2) + (1/4) / (X - 2)
Step-by-step explanation:
1 / x²-4 = 1 / (X+2) * (X-2)
1 / X²-4 = (A / X+2) + (B / X-2) = (AX - 2A + BX +2B) / X² -4
∴ 1 = (A + B) * X - 2 (A - B)
A + B = 0
- 2 (A - B) = 1
A - B = - 1/2
∴ 2A = - 1/2
A= - 1/4
B= 1/4
1 / X² -4 = (- 1/4) / (X+2) + (1/4) / (X - 2)
