A circle of finite radius with points

(- 2, - 2), (1, 4),

(k, 2006)

https://math.stackexchange.com/questions/1720599/a-circle-of-finite-radius-with-points-2-2-1-4-and-k-2006-can-exist

Given three arbitrary non-collinear points on a plane, we can always find one and only one circle whose circumference passes through them. So the answer is

(D)

infinite values of

k

A triangle's coordinates are

(- 2, 1), (- 6, 1),

(- 4, 5)

https://socratic.org/questions/a-triangle-s-coordinates-are-2-1-6-1-and-4-5-after-the-triangle-is-rotated-clock

New coordinates are

(- 1, - 2)

(- 1, - 6)

(- 5, - 4)

Explanation: A clockwise rotation of

270^{\circ}

What is the cross product of

< 3, 1, - 6 >

< - 2, 1, 8 >

< 14, - 12, 5 >

Explanation: we want

< 3, 1, - 6 > \times < - 2, 1, 8 >

this is found by calculating the determinant

What is the slope of the line perpendicular to the line passing through the points

(8, - 2) and (3, - 1)

https://socratic.org/questions/what-is-the-slope-of-the-line-perpendicular-to-the-line-passing-through-the-poin

m = 5

Explanation: Find the slope of the line joining the two points first.

m = \frac{y _{2} - y _{1}}{x _{2} - x _{1}}

m = \frac{- 1 - ( - 2 )}{3 - 8} = \frac{1}{- 5}

What is the slope of the line passing through the following points:

(- 2, 0), (- 7, 0)

https://socratic.org/questions/what-is-the-slope-of-the-line-passing-through-the-following-points-2-0-7-0

slope = 0

note that the y-coordinates of the 2 points are 0

this means that the line is the x-axis with a slope of 0
