How can you tell by looking at the coordinate of a point whether the point is on the x-axis or y-axis?
the x coordinate is always before the y coordinate just like in the alphabet
Is the line that crosses the y-axis called a y-intercept or a x-intercept?
A line is just a line, but the y-coordinate (the point where the line intersects the y-axis) is termed the y intercept. This point has an x coordinate that is always zero and the y coordinate can be positive, zero, or negative
Are all parallelograms a quadrilaterals always sometimes or never?
-- A parallelogram is always a quadrilateral. -- A quadrilateral is sometimes a parallelogram.
Three points are sometimes never or always collinear?
sometimes
Are two obtuse triangles always similar?
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
Is a horizontal line left to right?
Yes, it is. Think of the horizon. A horizontal line is parallel to the horizon.
What is the horizontal or vertical number line on a coordinate plane?
They are the axes. Usually horizontal = x-axis, vertical = y-axis. But that need not always apply. In a displacement-time or speed-time graph, for example, the horizontal axis = t-axis (for time).
How do you find the coordinates of a point on as coordinate grid?
a coordinate grid is written as the horizontal line is the values of the x-coordinate and the vertical line is the values of the y-coordinate. lets say you have the points (2,3) whenever you see this ( , ) this is called an ordered pair. the x-coordinate always comes first and the y-coordinate comes second.. like this.. (x,y) in the coordinate i gave as an examples (2,3) the 2 is the x-coordinate and 3 is the y-coordinate. first take the x-coordinate. since the horizontal line is for the x-values then you apply the 2 to this horizontal line. the 2 implys that you go over 2 units. since the number 2 is positive you go to the right of the intersection of the two lines. if the two was -2 then you would go left. now take the y-coordinate. since the vertical line is for the y-values then you apply the 3 to the vertical line. the 3 implys that you go up 3 units. since the 3 is positive then means you go up instead of down. if the 3 were a -3 then you would go down three units. now that you have gone 2 units to the right and then 3 units up you should have a dot that is above the horizontal line and the dot should also be to the right of the vertical line. always remember that the point at which your horizontal line (this is for your x-values) and your vertical line (this is for your y-values) is called the point (0,0) this is called the origin. when you are trying to find the coordinate points always start counting from the origin (0,0).
In an ordered pair it does not matter which number is called the x coordinate and which is called the y coordinate?
The first coordinate always is called the "x" coordinate, because it goes on the "x" axis, while the second coordinate is always called the "y" coordinate because it always goes on the "y" axis.
What slope do horizontal lines always have?
Horizontal lines always have a slope of 0.
Is y coordinate always a negative number?
No, the y-coordinate can be positive or negative.
Why are high capacity pumps usually in a vertical position rather than a horizontal position?
This is not always true. High velocity pumps can be found in horizontal configurations too. It all depends on the application (sometimes the manufacturer) whether it will be a horizontal of vertical pump.
The first number in an ordered pair is always called the y coordinate and the second number is always called the x coordinate?
false
Can the abscissa and ordinate of the origin have different values in a graph?
The horizontal x and vertical y axes on the Cartesian plane are perpendicular to each other and they intersect at the point of origin whose coordinate is always at (0, 0)
Do you do the x or y coordinate first?
The X coordinate always goes first think a baby crawls before it walks
What is always graphed on the Y-axis?
Y-coordinate
On a coordinate grid, does X or Y come first?
on a coordinate grid, X always comes before Y
