Answer:
The equation of a parallel line would be y = 2x + 4
Step-by-step explanation:
In order to find the equation of this line, we first have to note that paralell lines have same slopes. Therefore, since the original line has a slope of 2, we know the new line will have a slope of 2. Now we can use that information along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 8 = 2(x - 2)
y - 8 = 2x - 4
y = 2x + 4

Answer:
Wheres the actual graph with the quadrants?
Step-by-step explanation:
Let f be a function having domain in the set X, and range in the set Y. Then f would be invertible if there exists a function g having domain Y and range X, such as:

In other words, the function
is applied to an input x, and gives an outcome of y, then its inverse function, let say
, can be applied to y to give the result of x.
In other words,
y = f(x) if and only if x = g(y)
For example, considering the function

the inverse is:
