Step 1

<span>Find the two perfect square numbers it lies between.
</span>

<span>Solution:
</span>4²= 16 and 5² = 25, so lies between 4 and 5.

step 2

Divide 22 by 4. 22/4 = 5.5 (you can round off your answer)

step 3

Average 5.5 and 4. (5.5+4)/2 = 4.75

step 4

repeat step 2

Divide 22 by 4.75. 22/4.75 = 4.6316

step 5

repeat step 3

Average 4.75 and 4.6316. (4.75+4.6316)/2 = 4.6908

the answer is

4.69

A line passes through the points (-6, 4) and (-2, 2). Which is the equation of the line?

cupoosta [38]

Answer:

$\displaystyle y=-\frac{1}{2}x+1$

Step-by-step explanation:

The equation of any line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Two points are given: (-6,4) and (-2,2). Calculating the slope:

$\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}$

The equation of the line is, so far:

$\displaystyle y=-\frac{1}{2}x+b$

To calculate the value of b, we use any of the given points, for example (-6,4):

$\displaystyle 4=-\frac{1}{2}(-6)+b$

$\displaystyle 4=3+b$

Solving:

b = 1

The equation of the line is:

$\boxed{\displaystyle y=-\frac{1}{2}x+1}$

We can see none of the choices is correct.
