Therefore x2=9+y2. And x is the square-root of that (with two values plus and minus). Choose a value of y, and work out x2 and therefore the values of x. Plot the two (+ and -) on a graph and continue for more values of y.

How do you graph x2 plus y2 is less than or equal to 9?
It is the circular disc with centre at the origin and radius = 3 units.
What is the standard form of the equation of the conic section given below x2-y2-6x-2y 60?
Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68
What is the slope of a line passing through the points 1 9 and -3 16?
The equation to figure out a slope is y1 - y2 / x1 - x2. In (1,9) and (-3,16), 9 is y1 and 16 is y2. 1 is x1 and -3 is x2. Now you have -7/4, which is your slope!
The equation for the circle below is x2 plus y2 81. What is the length of the circle's radius?
9 (APEX)
How do you graph x2 plus y2 equals 9?
Draw a circle with its center at the origin and a radius of 3.
Find the radius for a circle with the equation x2 plus y2 equals 9?
Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..
What is the radius of x2 plus y2 equals 9?
X2 or 2 times x?
How do you draw a circle with the diameter of 6 on a graph?
If you want to have an center point of zero you use the equation x2+y2=r2. In this case x2+y2=9.
What is the radius for a circle with the equation x2 plus y2 equals 9?
Equation of a circle centre the origin is: x2 + y2 = radius2 ⇒ radius = √9 = 3.

What is the graph of y equals x2-7?
9
How do you graph x2 plus y2 is less than or equal to 9?
It is the circular disc with centre at the origin and radius = 3 units.
How do you use algebraic reasoning to find a way to graph X2 plus Y2 equals 9 using a graphing calculator Explain why it doesn't look like a circle and also try and how you could alter the scr?
When graphing, you typically want an equation in the form y = f(x). To convert your equation for a circle to this form: Y2 + X2 = 9 Y2 = 9-X2 Y=sqrt(9-X2) This equation will not look like a circle when it is graphed because the square root of any real number is always positive, so only the positive half of the circle will be graphed.
Factorise x2 minus y2 plus 9x minus 9y?
x2 - y2 + 9x - 9y =(x2 + 9x) - (y2 + 9y) =x(x + 9) - y(y + 9)================================Another way to go after it:x2 - y2 + 9x - 9y =(x2 - y2) + 9x - 9y =(x + y) (x - y) + 9 (x - y) =(x + y + 9) (x - y)
