Perpendicular lines, slope is opposite and reciprocal

so slope of new line = - 4

passes through (-2, -6) in point-slope form

y + 6 = -4(x + 2)

Answer is C. y + 6 = -4 (x + 2)

Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

and $a^{-1}=\dfrac{1}{a};\ a^{-n}=\dfrac{1}{a^3}$

$3^{-1}\cdot(4\cdot6)\cdot2^{-3}=\dfrac{1}{3}\cdot24\cdot\dfrac{1}{2^3}=\dfrac{24}{3}\cdot\dfrac{1}{8}=\not8^1\cdot\dfrac{1}{\not8_1}=1$

((1+4i)/i) +(1+i)/(2+5i)
(((1+4i)*(2+5i)) +((1+i)*i))/(i*(2+5i))
((2 + 8i + 5i +20i²) + (1i + i²) )/ (2i + 5i²)
((2 + 13i -20) + (1i -1))/(2i - 5) where i² = -1
((14i - 19) +0)/2i - 5
(14i -19)/(2i - 5)

Which points are 4 units apart?

xz_007 [3.2K]

The points that are 4 units apart are B and D

<h3>Complete question</h3>

Which points are 4 units apart? On a coordinate plane, point A is at (-2, 4), point B is at (3, -6), point C is at (-1, 0), point D is at (3, -2).

B and C

C and D

A and C

B and D

<h3>How to determine the points?</h3>

To do this, we simply calculate the distance using the following equation

$d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2$

Using the given points, we have:

$BC = \sqrt{(3+ 1)^2 + (-6 -0)^2} = 7.2$

$CD = \sqrt{(-1 - 3)^2 + (0 +2)^2} = 4.5$

$AC = \sqrt{(-2 + 1)^2 + (4 -0)^2} = 4.1$

$BD = \sqrt{(3 - 3)^2 + (-6 +2)^2} = 4$

Hence, the points that are 4 units apart are B and D
