No, linear equations don't have x2.

Equation with x and y are usually linear equations.

Equations with either x2 or y2 (but never both) are usually quadratic equations.

no, because xx=x squared, and x squared is not linear

Do all graphs of linear equations have x intercepts?

YES, all linear equations have x-intercepts. because of the x, y has to be there 2!

How do you know if an equation is not linear?

Linear equations come in the form y=mx+b or y=mx-b, where x and y are the variables x and y and b is a constant (like 3). All other equations are non-linear. Linear equations has a power of 1! as long as the X has a power of 1, it is a linear equation.

Is y equals 5x squared -3 a linear function?


Is y equals x squared 2 plus 5 linear?

No, to be linear, both the power of x and y need to be 1. Since x is squared, the power of x is 2.

Do linear equations form a line?

Yes, the graph of a linear equation can be a line. There are special cases, sometimes trivial ones like y=y or x=x which are linear equations, but the graph is the entire xy plane. The point being, linear equations most often from a line, but there are cases where they do not.

How do you solve linear equations when the given is x equals -3 y equals 5?

If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?

What are differences between linear an exponential equations?

A linear equation is one in which the variable is raised to the first power (i.e. x, not x squared or x cubed or anything else). An example would be y = mx + c. In an exponetial equation the variable is part of the exponent, e.g. y = 3^x + c.

Why are not all functions linear equations?

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

What is a system of linear equations?

A system of linear equations determines a line on the xy-plane. The solution to a linear set must satisfy all equations. The solution set is the intersection of x and y, and is either a line, a single point, or the empty set.

Is y equals 9 plus 3x linear?

y=9+3x is linear because there is only one value of x so it will go up proportionally, for instance if x=1 then y=12, x=2 y=15, x=3 y=18. they will always go up by three, only equations with multiple xs, eg x squared+4x+6 is non linear and x cubed-9 is non linear.

What is x y squared?

x y squared is a formula For Example- Say x was 3 and y was 5 squared Then it would be 3 squared times 5 squared 9x25=225 That would be your result..... Although... If the variables had no numbers in the equations answer... Then the answer would stay the same x y (squared)

Is x squared plus y equals 7 linear?

no you smell

Why is function and linear equation difference?

Functions and linear equations are the same in that they both deal with x and y coordinates and points on a graph but have differences in limitations, appearance and purpose. Often, functions give you the value of either x or y, but linear equations ask to solve for both x and y.

Is x squared plus 7x-30 equals 0 a linear equation?

No, It's a a quadratic equation because you have X squared.

Is the equation 3x-4 equals 12 linear or non linear?

It is a linear equation. The highest power of x in the equation is 1 (3x1-4=12) so its "degree" is 1, and equations of "degree 1" are called linear equations.

Example equations of linear equations?

y=3x+2 y-4x=9 These are examples of linear equations which is a first degree algebraic expression with one, two or more variables equated to a constant. So x=2 is a linear equation as is y=1 but x2 =1 is not since the variable, x , has degree 2.

What are the solutions to -x squared plus 2x plus 4 and x-2?

These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.

How can you use coordinate graphs to solve linear equations and linear inequalities?

To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.

Is 3x plus 27 equals 8 a quadratic function?

No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
