How many triangles are there in a three by three grid?
9 squares = 18 triangles * * * * * 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.
What is the equation of the line passing through the points -2.5 -0.5 and 4.5 -1 on the coordinated grid?
Points: (-2.5, -0.5) and (4.5, -1) Slope: -1/14 Equation: 14y = -x-9.5 or x+14y+9.5 in its general form
What is the approximate distance between the points (1-2) and (-93) on a cooridinare grid?
If you mean points of (1, -2) and (-9, 3) then it works out as about 11
Which type of lines pass through points 4 6 2 3 and 6 5 3 3 on a grid?
The lines that pass through points 4 -6 2 -3 and 6 5 3 3 on a grid are the lines y=x.
What is the approximate distance between the points (-5 1) and (-2 3) on a coordinate grid?
3.61 units
Why was the number grid invented?
to plot points
What is the first thing you have to do when measuring the grid azimuth between two points?
plot the points
How do you graph a picture on a coordinate grid?
it is basically easy and you have to plot the points
What is a grid that has an x and y-axis to plot points?
It is the Cartesian plane
What is a coordinated grid?
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.
What do you create when you overlap a horizontal number line and a vertical number line?
you would get a grid that you can plot points on.
What is the definition of the words plot points?
When you plot a point you are using coordinates to find a certain point on a grid. In fiction, a plot point is an event in the exposition which will have ramifications later in the story.
When would you need to plot points on a coordinate grid?
You need an x axis, y axis, and 4 quadrants.
A hexagon has a grid on it the height of the hexagon is 2units what would be the approximate area?
300 thak you:)
How many triangles can you make on a 3X3 grid?
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.

Which type of lines pass through points (-5 -3) (-3 3) and (7 9) (5 3) on a grid?
From a rough sketch they appear to be parallel lines but for a more accurate answer plot the points on the Cartesian plane
