its (-2 , 1) not (-2 1)
A linear equation/function can have division in the equation, as long as a non-constant variable is not the denominator.Examples:1 y = (1/2)x + 2 Linear2 y/3 = (x - 1)/3 Linear3 y = 1/x + a Non linear
Yes, since y = x - 2 has the degree of 1 [or the highest exponent of the equation], x - 2 is the linear equation.
Without an equality sign it is not an equation.
y = 2x + 1 IS a linear equation!
A linear equation has no higher powers than 1. This is linear.

A non-linear equation is any equation which includes variables with a degree other than one. Therefore, any equation involving x2, x3, x4, .... would be non-linear. For example: y= 3x+2 is linear, because x and y are both degree 1 (no exponent) y= 2x2 is non-linear, because x is degree 2.
y = 2x + 1 IS a linear equation!
A linear equation has no higher powers than 1. This is linear.
There can be linear equations with 1, 2, ... variables. Each of these is different since an equation with n variables belongs to n-dimensional space.

A linear equation is that equation in which a variable or variables has exponent equal to 1. For example, standard form of linear equation in one variable: a1x + a2x +.......+ anx = c Standard form of a linear equation : a1x + a2x +.........+ anx = c e.g. 4x + 3 =6, 3x + 6y + 5z = 2 etc.
2x - 1 = 1 is a linear equation in one variable. If 2x - 1 = 1, then we can add 1 to each side of the equation and get 2x = 2, then divide both sides of the equation by 2, and we arrive at the answer, which is x = 1.

The gradient of a linear equation is also known as slope. Slope is the (Change in Y)/(Change in X). Luckily there is a simple way to find out the slope in a simple linear equation. A simple linear equation can be written as: y = mx + b where m = slope (gradient) and b = y-intercept I assume your equation is x = 2y + 1. This may look like it fits the equation above but it does not. The equation needs to be solved for y. x = 2y + 1 (Subtract 1 from both sides) x - 1 = 2y (Divide both sides by 2) x/2 - 1/2 = y Now the equation is in the proper form. y = 1/2x - 1/2 Looking at the first equation: m = slope = 1/2. The slope (or gradient) is 1/2
In a linear equation, the highest power of all variables is 1. eg y = x + 3 In this example, the variable (x) has a power of 1 (remember, x1 is the same as x). Therefore, a linear equation. eg 2 y = x2 +7 eg 3 y = p3 + p - 89 In example 2 and 3, variables have a power higher than 1. Hence, they are non-linear equations.
