Is this a linear equation - xy equals 24?
no. its an exponential with a vertical zero axis
Is xy equals 6 a linear equation?
Yes. You can tell by the fact that both variables are raised to the first power.
Does 46 satisfy the linear equation xy?
no
Do linear equations form a line?
Yes, the graph of a linear equation can be a line. There are special cases, sometimes trivial ones like y=y or x=x which are linear equations, but the graph is the entire xy plane. The point being, linear equations most often from a line, but there are cases where they do not.
Is 6xy plus 3x equals 4 a linear equation?
No. In the variable x, alone, it is linear. In the variable y, alone, it is linear. But taken together, in x and y, you have a term which contains xy - that is, a term in which the powers of the unknowns add to 2. So the equation is not linear.
How do you graph the linear equation xy 4?
There are many ways to graph linear equations. One way that will always work it to pick some points, 3 is plenty. Pick and x value, plug it in and then find the y value. You will obtain a set or ordered pairs. Graph these and connect the dots. Voila------------- a line!
Are A linear equation determines a line in the xy-plane?
Yes, the world "linear" and "line" have the same root.
How do you find the y-intercept of the graph represented by the equation on 2x-xy equals 12?
-10
Is xy equals 1 a linear equation?
No because when you place x in terms of y, you get y = 1/x ( by dividing both the sides by x). This is not linear because the power of x is (-1) and for a linear relationship, you need the power of x to be (1).
Equation of the evolute for rectangular hyperbola xy equals cc is?

Can you think of any real-world situations that when drawn on an xy-plane might appear as a shifted or stretched graph of a basic equation such as y equals x or y equals x2?
baseball being thrown? soccer ball?
Is -1 equals xy a linear?
You mean -1 = xy , right? If we think of y against x, then it's like y = -1/x .... It's not linear. But if we consider y against 1/x , it's linear....
