Since you know the values of the two variables, a and y, plug it into the expression like this: 2a3 - 3ay = 6a - 3ay = 6(-1) -3(-1)(2) = -6 -3(-2) =-6 + 6 = 0
The slope of a line between Points 1 and 2 is defined as m = (Y2 - Y1) / (X2 - X1) where coordinates for Point 1 is (X1,Y1) and Point 2 is (X2,Y2). So if the value of Y2-Y1 = 0 then the Slope is zero. If the value of X2 - X1 = zero then the equation is undetermined because you can't solve an equation with a 0 value in the denominator. or m = (Y2 - Y1) / 0
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
You don't "solve" an expression. You can solve an equation; an expression can be simplified or otherwise manipulated, and if you know the value of "x" (in this case), you can evaluate its value.
Without an equality sign the given expression is not an equation and so therefore finding the value of x is not possible.
+1/0 or -1/0 or 0/0
The expression Y-2 is 1/Y2. The reciprocal of 1/Y2 is Y2.

x = -1y = 33x2 - y2 = 3 (-1)2 - (3)2 = 3 (1) - 9 = -6
The expression would be written as 16 The value of the expression is 1. 1 x 1 x 1 x 1 x 1 x 1 = 1
x = 1 / y2 where: x is the dependent variable y is the independent variable
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2

Yes.
If you should mean x-1 = 2y Solved for x: x = 2y + 1 Solved for y: y = (x-1)/2
equation is an expression equated to a value..what you have written is an expression. when equated to a value or any other expression makes it an equation.
