What is the quadrant with positive x and y coordinates?
That would be Quadrant I
In a correlation coefficient the difference between r and r squared?
r is correlation and can be positive or negative. If you want an analogy, consider it like the slope of a line. If the slope is negative, the line slopes downward and therelationship between the two variables (x & y) are inverse. That is, as x increases, y will decrease. If r is positive, then the line slopes upward and as x increases so does y. Now if x equals or is close to zero, there is no significant relationship between the two variables ... as x increases y does not change or fluctuates between positive and negative changes. The closer r is to +1 or -1, the stronger the relationship between x and y.
How do you use a coordinate plane?
We assign coordinates to point on the plane and use those coordinates to tell us about the points. For example, the distance formula tells us how far apart they are, the midpoint formula tells us where there midpoint is. All of these and much more depend looking at a point as an ordered pair, (x,y) in the coordinate plane.The coordinate system is determined by the two directed lines and the given unit length. When the directed lines intersect at a right angle, the system is Cartesian, and (x,y) are Cartesian coordinates of the point. Normally, x-axis and y-axis are chosen so that an anticlockwise rotation of one right angle takes the positive x-direction to the positive y-direction. There are other methods of assigning coordinates to points in the plane. one such is the method of polar coordinates. The coordinate plane is the main idea in analytic geometry.
What are quadrants of a graph?
Divide the graph into 4 parts and each part is a quadrant. Traditionally, we use the x and y axis to divide it. The portion of the graph with positive x and y coordinates is the first quadrant, The second has positive y values and negative x values, while the third quadrant has both negative x and negative y values. The last is the fourth quadrants which is below the first quadrant. It has positive x values and negative y values. If you made the origin, the point (0,0) the center of a clock, the first quadrant is between 3 and 12 and the second between 12 and 9, the third between 9 and 6 and the fourth between 12 and 3.
What does a positive correlation between variables x and y imply?
It implies that an increase in x is accompanied by an increase in y. And similarly, they decrease together.
What exists if the y-coordinates increase as the x-coordinates increase?
Positive slope.
In which quadrants do the x and y coordinates have the same signs?
The x and y coordinates are both positive in Q I. They are both negative in Q III
What is the quadrant with positive x and y coordinates?
That would be Quadrant I
Which Quadrant has positive x and y- coordinates?
That's Quadrant - I .
Where does a point with both the x- and y-coordinates positive lie?
It lies in quadrant I.
What is a positive or negative relationship on a graph?
If a function Y is dependent on X. if X increases in value then Y also increases then we call this a positive relationship. If X increases in value then Y decreases or vice versa then we call this a negative relationship.
When reflecting a figure in the x-axis will you change all of the figures X coordinates or the y coordinates?
The y-coordinates.The y-coordinates.The y-coordinates.The y-coordinates.
What points lie in the fourth quadrant?
The negative y coordinates and positive x coordinates lie in the IV quadrant on the Cartesian plane
Why are roman numerals used backwards on coordinate planes?
It has to do with where the x and y coordinates are positive and negative.
Which point is in Quadrant 1?
any set of coordinates with both the x and y values positive.
What type of number is to the right of zero on the x axis and above zero on the y axis?
Positive x- and y-coordinates of a point in the first quadrant.
Which comes first x axis or the y axis in math?
It is the x coordinates followed by the y coordinates i.e (x, y)
