Answer:
2
to find the slope you get the rise which is the difference between the y coordinates over the run which is the difference between the x coordinates. so 6/3=2
Answer:
Base = 3 cm
Step-by-step explanation:
Area of a triangle = 
Let h = height
base = 2 times the height - 5; b = 2h-5
Area = 6 cm²
A = 
Multiply 2h(h) -5(h)
Multiply both sides by 2 to remove the fraction
12 = 2h²- 5h
2h ² - 5h - 12 = 0 Set the equation = 0 and factor
(2h + 3)(h - 4) = 0
2h + 3 = 0 or h - 4 = 0
2h = -3 h = 4
h = -3/2 or h = 4 Answer can not be negative so h = 4cm
The base is 2(4) - 5; The base = 8 - 5; base = 3 cm

Given:
Hyperbola with directrices at y = ±2 and foci at (0, 6) and (0, −6).
To find:
The equation of hyperbola.
Solution:
We have, directrices at y = ±2 so this hyparabola is along the y-axis.
The standard form of hyperbola is
...(i)
where, (h,k) is center, foci are
and directrix are
.
On comparing foci, we get


On comparing directrix we get




Now,




Putting
, we get


Therefore, the equation of hyperbola is
.
