Answer:
If you're given two points (x1, y1) and (x2, y2), the slope is (y2 - y1)/(x2 - x1);
We have ( 7 - 3 )/(6 - 2) = 4 / 4 = 1;
Step-by-step explanation:

Answer:
Option 2
Step-by-step explanation:
We have been given a quadratic equation
First step in completing method square is to make the coefiicient of 1
Since, in given quadratic equation coefficient of is already 1. we will proceed to the next step which is add and subtract square of the half of coefficient of x in given quadratic equation.
Here, half of coefficient of x that is 8 would be 4 so we will add and subtract in given quadratic equation we will get
Now, we will proceed to the third step that is making the whole square formula according to the terms
Here, we can see that we are geeting the formula of from
The equation will become
After simplifying we will get
After further simplification we will get
After more simplification we will get
Hence, we will get the value of x which is
The solution to the quadraticequation x² - 8x + 5 = 0, using the completing-the-square method is x = 4 ± √11
Option B is the correct answer.
We have,
To solve the quadratic equation x² - 8x + 5 = 0 using the
completing-the-square method, follow these steps:
Move the constant term (5) to the other side of the equation:
x² - 8x = -5
Take half of the coefficient of the x-term (-8) and square it:
(-8/2)² = 16
Add the squared value to both sides of the equation:
x² - 8x + 16 = -5 + 16
x² - 8x + 16 = 11
Rewrite the left side of the equation as a perfect square:
(x - 4)² = 11
Take the square root of both sides, considering both positive and negative square roots:
x - 4 = ±√11
Solve for x by adding 4 to both sides:
x = 4 ± √11
Therefore,
The solution to the quadraticequation x² - 8x + 5 = 0, using the completing-the-square method is x = 4 ± √11
