What does xy 0 mean?
xy = 0
That is, if a point in the plane is a solution of xy = 0, either its x-coordinate equals 0 (which means that point is in S, the y-axis) or its y-coordinate equals 0, (which means that the point is in V , the x-axis).
Is X Y 0 a function?
It is not a function (as it was pointed out in a comment), but a relation, like a circle (a set of ordered pairs): R={(x,y)|xy=0}.
What does it mean when an equation equals itself?
This means that it doesn’t matter what value we substitute for , the equation will always be true. Go ahead and try plugging in a couple of your favorite numbers to verify this is true. equal to itself? Always!
Is xy 0 a plane?
The confusion appears to arise from Strang conflating equations and sets. I.e. “2x−y=0” isn’t really a plane or a line; it’s just an equation.
What does it mean by Y 0 )= 1?
In math, y(0)=1 y ( 0 ) = 1 represents a function such that when given the input value of zero, it will return an output value of 1.
What is the slope of xy 0?
Using the slope-intercept form, the slope is −1 .
What occurs when the y value is 0?
an x-intercept is a point in the equation where the y-value is zero, and. a y-intercept is a point in the equation where the x-value is zero.

What is the XYZ plane?
The xy-plane is the plane that contains the x- and y-axes; the yz-plane contains the y- and z-axes; the xz-plane contains the x- and z-axes. These three coordinate planes divide space into eight parts, called octants.
What is the meaning of Y 0 )= 0?
Your equation y = 0 is a linear equation since the variable has no exponent. Remember, the slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
What is the Y-Y value at x = 1x = 1?
The final answer is 1 1. The y y value at x = 1 x = 1 is 1 1. Create a table of the x x and y y values. Graph the line using the slope and the y-intercept, or the points.
What is the difference between the x-axis and the Y-axis?
The x-axis is usually the horizontal axis, while the y-axis is the vertical axis. They are represented by two number lines that intersect perpendicularly at the origin, located at (0, 0), as shown in the figure below.
What is the y-intercept of a graph?
Likewise, the y-intercept is a point at which a graph intercepts the y-axis. The y-coordinate of an x-intercept is always 0, and the x-coordinate of a y-intercept is always 0. Given an equation, plugging in x = 0 will yield the y-intercept and plugging in y = 0 will yield the x-intercept.
How do you find the x-intercept of an equation?
Select two x x values, and plug them into the equation to find the corresponding y y values. Tap for more steps… Find the x-intercept. Tap for more steps… To find the x-intercept (s), substitute in 0 0 for y y and solve for x x. Rewrite the equation as x = 0 x = 0. x-intercept (s) in point form. Find the y-intercept.
