What can be represented by coordinates x and y?
You could show the y-axis by distance and the x-axis by time.
Graph the equation x plus y 3?
Put a dot on the x axis at x=3 and a dot on the y axis at y=3 and draw a straight line between them.
What is the y-intercept of a linear equation?
The y-intercept of a linear equation is the point where the graph of the line represented by that equation crosses the y-axis.
What is an equation of the axis of symmetry of the parabola represented by y equals -x2 plus 6x-4?
Line of symmetry: x = 3
How many quadrants x-axis and y-axis divide the coordinate plane into?
There are four quadrants (hence the name "quad"). Draw a crossing vertical line (Y axis) and horizontal line (X axis). The areas to the "top right", "bottom right", "bottom left" and "top left" are the four quadrants. Which quadrant any given co-ordinate lies in depends upon the sign of the X & Y values. eg (+X,+Y) (+X,-Y) (-X,-Y) or (-X,+Y) respectively.
What is a y-axis?
y axis in nothing but any vertically represented one...
What can be represented by coordinates x and y?
You could show the y-axis by distance and the x-axis by time.
What quantity is represented on the x- axis?
The horizontal coordinates are plotted on the x axis whereas the vertical coordinates are plotted on the y axis in the form of (x, y)
In the equation y equals 8x-3 the y-intercept is represented by the coordinate?
11
Which quadrant does the line representing the equation Y equals 7X pass through?
At what point does line represented by the equation 8x + 4y = -4 intersects the y-axis, and at what point in the negative direction of x-axis.
What do you start with x or y axis?
When answering a graph question it doesn't really matter what axis you look t first. That's the same when constructing a graph , you can draw either axis first (:
Graph the equation x plus y 3?
Put a dot on the x axis at x=3 and a dot on the y axis at y=3 and draw a straight line between them.
How do you construct a more than type cumulative frequency distribution?
Ogive (Cumulative Frequency Curve) There are two ways of constructing an ogive or cumulative frequency curve. (Ogive is pronounced as O-jive). The curve is usually of 'S' shape. We illustrate both methods by examples given below: Draw a 'less than' ogive curve for the following data: To Plot an Ogive: (i) We plot the points with coordinates having abscissae as actual limits and ordinates as the cumulative frequencies, (10, 2), (20, 10), (30, 22), (40, 40), (50, 68), (60, 90), (70, 96) and (80, 100) are the coordinates of the points. (ii) Join the points plotted by a smooth curve. (iii) An Ogive is connected to a point on the X-axis representing the actual lower limit of the first class. Scale: X -axis 1 cm = 10 marks, Y -axis 1cm = 10 c.f. Using the data given below, construct a 'more than' cumulative frequency table and draw the Ogive. To Plot an Ogive (i) We plot the points with coordinates having abscissae as actual lower limits and ordinates as the cumulative frequencies, (70.5, 2), (60.5, 7), (50.5, 13), (40.5, 23), (30.5, 37), (20.5, 49), (10.5, 57), (0.5, 60) are the coordinates of the points. (ii) Join the points by a smooth curve. (iii) An Ogive is connected to a point on the X-axis representing the actual upper limit of the last class [in this case) i.e., point (80.5, 0)]. Scale: X-axis 1 cm = 10 marks Y-axis 2 cm = 10 c.f To reconstruct frequency distribution from cumulative frequency distribution. When we write, 'less than 10 - less than 0', the difference give the frequency 4 for the class interval (0 - 10) and so on. When we write 'more than 0 - more than 10', the difference gives the frequency 4 for the class interval (0 - 10) and so on.

Is the y axis the dependent variable?
In most cases, yes, the y-axis represents the dependent variable in a graph or chart. This variable is typically influenced or affected by changes in another variable represented on the x-axis.
What is the y-intercept of a linear equation?
The y-intercept of a linear equation is the point where the graph of the line represented by that equation crosses the y-axis.
How did the x-axis and y-axis get their name?
Unknown variables are often represented by lower case letters in English: that is, x, y, z, w etc. When there are just two, they are usually denoted by x and y. A graph of these requires the two axes which are therefore called the x-axis and y-axis respectively.
How do you find the intercept of a line?
The y-coordinate of the point where the line cuts the y-axis If the line can be represented as y = mx + c, then c is the intercept
