Answer:
An equation of a line is written in the form y=mx+b. ”m” is the slope and ”b” is the y-intercept. So, substituting the values, the equation is y=-4x+1.

Answer:
Part 1:
or 
Part 2: 
Step-by-step explanation:
To start things off, you must put everything on the opposite side of y so that you only have the y variable left.
In this case, put x onto the other side, making it negative since it's flipped, so you get
(since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:


Then in this case you turn y=f(x), but the system did it for you, so all you have to put is
.
For the second part you must replace x with 2 since you need to find f(2).

Your answer for part 2 is
.
The roots of the given polynomials exist

<h3>What is the formula of the quadratic equation?</h3>
For a quadratic equation of the form
the solutions are

Therefore by using the formula we have

Let, a = 1, b = -16 and c = 54
Substitute the values in the above equation, and we get

simplifying the equation, we get



Therefore, the roots of the given polynomials are
, and
.
