How do you determine direct and inverse proportion on graphs?
If the variables x and y are in direct proportion then the graph of y against x is a straight line through the origin. If the variables x and y are in inverse proportion then the graph of y against x is a rectangular hyperbola. Alternatively, the graph of y against 1/x (or 1/y against x) is a straight line through the origin.
What shape is the graph for y equals 3x2 look like?
It is a parabola emanating from the origin. Plot some +/- points when X = 1; Y =1 (+/-) when X = 2; Y = 12 (+/-) when X = 3; Y = 27 (+/-) same for when X = -1,-2,-3 etc
How do you graph equation y equals x plus 4?
y=x+4 To graph this, you need to find the y-intercept in the equation which is 4. Plot that on the graph by going up 4 from the origin (0,0). Next, go right one, up one and plot. Then, right one, up one again.
What are the x and y axis used for?
The x and y axes are horizontal and vertical number lines that intersect each other at right angles at the point of origin (0, 0) on the Cartesian plane and is used to plot graphs on it by given sets of coordinates.
What is the symmetry to y-x3?
Let F(x,y) = y - x^3 Note that (-x)^3 = -(x^3) This suggests that F(-x,-y) = -F(x,y) (-x,-y) represents the point (x,y) reflected through the origin. You could say the function F has anti-point symmetry -- each point (x,y,F) is reflected through the origin at (-x, -y, -F).
What is the origin of zero?
In a rectilinear (xy) plot where a point is represented by a pair of numbers (x,y), the origin is normally (0,0). That is, at the origin, x=0 and y=0.

What do you plot first x or y?
x
What is the origin of the x and y axis?
The origin of the x and y axis, is (0,0).
How do you graph equation y equals x plus 4?
y=x+4 To graph this, you need to find the y-intercept in the equation which is 4. Plot that on the graph by going up 4 from the origin (0,0). Next, go right one, up one and plot. Then, right one, up one again.
What is a rectangular coordinate grid?
a grid in a rectangular shape with a x axis and a y axis.
Is -6 on the y axis considered to be on the origin?
No. The origin is the place where the x-axis and the y-axis cross. 'x' and 'y' are both zero there.
The point where x and y axis meet?
It is the origin
How can you name a point on a graph?
Compare it's position to the origin. The x coordinate is the number of units to the right of the origin. (If it is to the left of the origin the x coordinate is negative.) The y coordinate is the number of units above the origin. (If it is below, the y coordinate is negative.) The point is denoted (x,y) with the x coordinate in place of the x and the y coordinate in place of the y.
The point where the x and y axis meet?
origin
How do you plot y equals -x into a graph?
y=-x Draw a straight line with slope -1 passing through (0,0). Or, plot (x,y) coordinates that satisfy the equation, and connect the dots.
