x2 + y2 = 1x2- x2+ y2= 1 - x2
y2 = 1 - x2
y =± √(1 - x

For a circle with center at (a,b), and radius r: (x-a)2 + (y-b)2 = r2
A parallel equation has the same slope to the given equation. Note that your equation is in slope-intercept form; when an equation is solved for "y" (y = ...x + ...), the number in front of the "x" is the slope. Solve each of the other equations for "y" (if they are not already solved for "y"), and check the number in front of the "x".
It is a non-linear equation in x and y. The equation cannot be solved without further information.
y-3x+2 is an expression, not an equation. An expression cannot be solved.
A circle centre (0, 0) and radius r has equation x² + y² = r² The circle x² + y² = 36 has: r² = 36 → radius = 6
A unit circle is a circle of radius 1. If it's center is at the origin of an xy-coordinate system, then the equation is x (squared) + y (squared) = 1
The unit circle is a circle that can be used to find trigonometric functions. The equation of the unit circle is x^2 + y^2 = 1. So it is any circle with radius 1.

Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
The equation of the circle is: x^2 + y^2 = 81
