A direct variation must satisfy both of two conditions:
1. It must pass through the origin (which this graph does)
2. It must be a straight line (which this graph does not satisfy).
Therefore the given graph is NOT a direct variation.

Corollary:
If a function satisfies both of the above conditions, it has an equation of the form 
y=kx
where k is a constant not equal to zero.

This way, we can tell a direct variation even from an equation.
Note: y=4x+2 is NOT a direct variation because the "+2" makes the straight line not pass through the origin.
y=2x^2 is not a direct variation because a function containing any other power of x is no longer a straight line.

It is not direct variation because it does not follow the equation 
y = slopex
THE points do not make the equation true .

U(8, 9) and V(2, 5) are the endpoints of a line segment. What is the midpoint M of that line segment?
Crazy boy [7]

Answer:

(5, 7 )

Step-by-step explanation:

Given 2 points (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

here (x₁, y₁ ) = U(8, 9) and (x₂, y₂ ) = V(2, 5), thus

midpoint = [0.5(8 + 2), 0.5(9 + 5) ] = [0.5(10), 0.5(14) ] = (5, 7 )

If the midpoint of two points is (2,5) and one of the endpoints is (6,3), what is the other endpoint?
aleksley [76]
To answer this question, you need to draw out the graph first. By doing so, you will be able to know where the other endpoint is located. (Fig. 1)

Next, count the number from the midpoint to the endpoint to determine the coordinates for the other endpoint. (Fig. 2)
Example: From (2, 5) to (6, 3)
x: 2 to 6 = 4 steps
y: 5 to 3 = 2 steps

From there, you can determine the other endpoint like this.
Example: From (2, 5) to the other endpoint
x: 2 to x1 = 4 steps
y: 5 to y1 = 2 steps

Therefore, x1 = -2 and y1 = 7
Other endpoint: (-2, 7)

Sorry for the messy drawing, it is hard to draw without a pen. Haha... hope this helps :)

DOES A PLANE CONTAIN ATLEAST TWO POINTS THAT LIE ON THE SAME LINE?
romanna [79]
Your question evokes several thoughts. Here are two of them:. 1). It takes 3 points not all on the same line to define a plane. 2). Two points ALWAYS lie on the same line.
