That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.

There is no equation on the list you're showing that has the same graph as [ 4x + 8y = 12 ].

A hyperbola is another form of a conical section graph like a parabola or ellipse. Its general form is x^2/a - y^2/b = 1.

Equation of a circle when its centre is at (0, 0): x^2 + y^2 = radius^2 Equation of a circle when its centre is at (a, b): (x-a)^2 + (y-b)^2 = radius^2

It is y = x + 4

The graph of that equation is a circle, centered at the origin, with radius = 2 .

No. It can also be a circle, ellipse or hyperbola.

any graph that is not represented by a line,ie: parabola, hyperbola, circle, ellipse,etc

The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph

you should watch that the graph equals 100 percent

Just like any other equation, you can set up a table of x values, and calculate the corresponding y values. Then plot the points on the graph. In this case, it helps to have some familiarity with quadratic equations (you can find a discussion in algebra books), and recognize (from the form of the equation) whether your quadratic equation represents a parabola, a circle, an ellipse, or a hyperbola.

The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
