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.

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!
Why can linear equations and linear inequalities be solved the same way?
Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.
If two linear equations are in standard form how can you tell that the graphs are parellel?
If the slopes are the same on both graphs, they are parallel, and will never touch.
What is 5x-6y equals 16 5x plus y equals 2 in linear equations and inequalities?
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
What are the uses of linear inequalities?
In question and answer logic answers are given and if they fall in an area bounded by the inequality then it is a good answer. After graphing three or more inequalities the vertexes are the possible maxima of the system of equations.
Why is it important the linear equations and inequalities?
There are many simple questions in everyday life that can be modelled by linear equations and solved using linear programming.
How are linear inequalities and linear equations the same?
They are not. An inequality cannot, by definition, be the same as an equation.
Can you solve system of equations by graphing?
Yes you can, if the solution or solutions is/are real. -- Draw the graphs of both equations on the same coordinate space on the same piece of graph paper. -- Any point that's on both graphs, i.e. where they cross, is a solution of the system of equations. -- If both equations are linear, then there can't be more than one such point.
What types of equations or inequalities describe points x y that lie on a circle?
Linear equations or inequalities describe points x y that lie on a circle.
Who made linear equations?
Descartes made the coordinate plane.
Does in linear graphs the slope of the line change with the x-coordinate?
No. A linear graph has the same slope anywhere.
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 linear equations were used for the first time?
Rene Descartes was a French mathematician who created the coordinate plane on which linear equations are plotted.
What does it mean by solving linear systems?
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
Can there be more than one point of intersection between the graphs of two linear equations?
Normally no. But technically, it is possible if the two linear equations are identical.
How are line graphs relates to math?
they express linear equations in a visible way
What outcome is not possible for the graph of a system of two linear equations?
the equation graphs
