I believe the answer is 2
Answer:

Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when x is 0) - Parallel lines always have the same slopes
<u>1) Determine the slope (m)</u>

The given line has a slope of -2. Because parallel lines always have equal slopes, we know that the line parallel to this would also have a slope of -2. Plug this into
:

<u>2) Determine the y-intercept (b)</u>

Plug in the given point (2,4) to solve for b

Add 4 to both sides to isolate b

Therefore, the y-intercept of the line is 8. Plug this back into
:

I hope this helps!
Answer:
Symmetric point: x = -1; (-1, 5)
Minimum of f: None; approaches -∞.
Maximum of f: y = 5.
Is f(x) a one-to-one: No, it fails the horizontal line test and is not injective.
Increasing from: -∞ to -1; (-∞, -1)
Decreasing from: -1 to ∞. (-1, ∞)
