The equation of the hyperbola is
The points on the graph are given as:
- (2, 0) and (-2, 0)
- (4, 0) and (-4, 0)
- Lines at: x = 1 and x = -1
The hyperbola can be represented as:
The points (2, 0) and (-2, 0) means that:
Square both sides
So, we have:
Also, we have:
a^2 = c^2 - b^2
Where c = 4
This gives
a^2 = 4^2 - 4
Evaluate
a^2 = 12
Substitute a^2 = 12 in
Hence, the equation of the hyperbola is

Answer:
y = -2x - 6
The y-intercept will be (0,-6)
One point will be at (1,-8)
The line will go downward since it is a negative slope
Step-by-step explanation:
y−2=−2(x+4)
Distribute
y - 2 = -2x - 8
Move the constant to the other side
y - 2 = -2x - 8
+2 = +2
y = -2x - 6
