y=x2
Not at all.Y = x2 is a continuous function.
It's the gradient, or the steepness, of a linear function. It is represented by 'm' in the linear formula y=mx+b. To find the slope of a line, pick to points. The formula is (y2-y1)/(x2-x1). See the related link "Picture of a Linear Function for a picture of a linear function.
The word linear means in a straight line. If the graph is a line, it is linear. Also, linear equations are of the first order; they contain a variable but not a square (or higher power) of a variable. If the equation contains x2 it is not linear.
In general, it is linear if it is of the form a1x1 + a2x2 + ... + anxn + a0 = 0where a1, a2, ... an and a0 are constants, and x1, x2, ... , xn are variable.If there are only two variables then usually x1 = x and x2 = y.

No, it is not.
A linear equation IS a function. A function can look like X2+X+C, or X3+0, or X+Y+C, or many other ways. The function X+Y+C is a function in two variables, and can be a linear equation.
A linear function is one in which the power of the function is only one. So, the graph of it would be a straight line. For example, x2 + x = y is not linear, because the highest power is 2. A main difference is, non linear functions have curves, where as a linear function is a straight line, with the exception of when the function has a power of 0, and it is technically a straight line.

Linear equations can be written as y = mx + b. Any other function would be non-linear. Some linear equations are: y = 3x y = 2 y = -2x + 4 y = 3/4x - 0.3 Some non-linear functions are: f(x) = x2 y = sqrt(x) f(x) = x3 + x2 - 2
It can be thought of as a function that does not graph to a line when plotted. For example, y=4 or y=5x are linear. But y=x2 or y=x1/2 or y=ln(x) are not linear
just solve for x. 1) add 3y6 to both sides 2x=3y6 2) divide both sides by 2 to get x by itself: x=3y6/2
