Can all the linear equations be graph using the intercept?

Yes - provided you allow both x and y intercepts.

Are linear equations and functions different?

All linear equations are functions but not all functions are linear equations.

Do linear graphs represent proportional relationships?

Do all linear graphs have proportional relationship

Are graphs representations of equations?

Line graphs may represent equations, if they are defined for all values of a variable.

How are linear equations and functions alike?

They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.

Are all linear equations functions Is there an instance when a linear equation is not a function?

Linear equations are always functions.

What are the linear systems?

A "system" of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.

What do all direct variation graphs have in common?

All direct variation graphs are linear and they all go through the origin.

What does it mean for a system of linear equations to have no solutions?

It means that there is no set of values for the variables such that all the linear equations are simultaneously true.

Is linear algebra and linear equations the same?

Linear Algebra is a branch of mathematics that enables you to solve many linear equations at the same time. For example, if you had 15 lines (linear equations) and wanted to know if there was a point where they all intersected, you would use Linear Algebra to solve that question. Linear Algebra uses matrices to solve these large systems of equations.

How do you write equations from graphs?

Assuming the graph is linear, all equations will follow the formula y = mx + c, where "mx" represents the gradient of the line; "c" is the y-intercept i.e. where the graph crosses the y-axis.

Why are linear equations called linear equations?

Because, if plotted on a Cartesian plane, all solutions to the equation would lie on a straight line.

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.

What similarities do all graphs of linear functions share?

They are all represented by straight lines.

Does every pair of linear simultaneous equations have a solution?

Actually not. Two linear equations have either one solution, no solution, or many solutions, all depends on the slope of the equations and their intercepts. If the two lines have different slopes, then there will be only one solution. If they have the same slope and the same intercept, then these two lines are dependent and there will be many solutions (infinite solutions). When the lines have the same slope but they have different intercept, then there will be no point of intersection and hence, they do not have a solution.

What is the parent function for ALL linear equations?

y = x

Must solutions to systems of linear equalities satisfy both equalities?

Any solution to a system of linear equations must satisfy all te equations in that system. Otherwise it is a solution to AN equation but not to the system of equations.

Which best describes a system of equations that has no solution?

An "inconsistent" set of equations. If they are all linear equations then the matrix of coefficients is singular.

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.

Who discovered linear equations?

View all Sir William Rowan Hamilton invented the linear equation in 1843.

Why do some graphs not start at the origin?

Because not all equations have the co-ordinates 0,0 in their data range.

How are tables and graphs like equations?

They all show the values for a set of variables for different situations or outcomes.

Are all linear equations functions?

yes yes No, vertical lines are not functions

What is a system of equations that has a solution of all points on one line?

Linear system

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
