"2 5" and "2 5" are the same point
if you meant one of them to be (5,2) then:
distance = root[18]
= whatever the square root of 18 is, is the distance between the points
0, 1, or 2, depending on how far apart a and b are.
They are 1 graphing unit apart.
They are both vertical lines.
They are opposite parallel lines with points of (-2, 2) (2, 2) and (-2, -2) (2, -2)
parrell
depends how far the two points are apart innit mush?
A coordinate grid is a grid that you plot points on. A coordinate grid is a 2-dimensional: system in which a location is described by its distance from two perpendicular lines called axes.
0, 1, or 2, depending on how far apart a and b are.
If you mean points of (1, -2) and (-9, 3) then it works out as about 11
They are 1 graphing unit apart.
3.61 units
They are both vertical lines.
They are opposite parallel lines with points of (-2, 2) (2, 2) and (-2, -2) (2, -2)
If you mean points of: (-5, 1) and (-2, 3) then the distance is about 3.61 rounded to two decimal places
perpendicular
The lines that pass through points 4 -6 2 -3 and 6 5 3 3 on a grid are the lines y=x.
The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.
