Which equation has the same solution as x^2-6x-14
2 answers:
So,
First, notice that all of the answer options are in completed square form. So all we have to do is complete the square for the initial equation and see which equation it matches.
Isolate the constant term.
Add the necessary amount to both sides (halve the x term and square it).
Factor the completed square.
This equation is identical to the equation in option B.
The correct answer is B.

Answer:
2y = x - 6
Step-by-step explanation:
First, we must find the slope of the current equation.
This is the number in front of the x.
Seeing as this is -2x, the slope of this line is -2
When finding the slope of a line perpendicular, you need to find the
So, in this case it is:
The negatives cancel out which leave
So the gradient is
Now, to find the equation of a line, you need to use:
y - y1 = m(x - x1)
Where ya and x1 are the values in the coordinates (2 , -2)
So y1 = -2, x1 = 2, and m is a half. Plug these values in:
y - - 2 =
We need to get rid of the half so we multiply the whole equation by 2:
2y - - 4 = (x - 2)
The minus and the negative turn into a positive:
2y + 4 = x - 2
And now simply move the +4 over to the other side, making it a negative:
2y = -2 - 4 + x
Simplify:
2y = x - 6
<h3>So the equation of the line is 2y = x - 6</h3><h2>Hope this helps!</h2>
