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.
YES, all linear equations have x-intercepts. because of the x, y has to be there 2!
Linear inequalities in two variables involve expressions that use inequality symbols (such as <, >, ≤, or ≥), while linear equations in two variables use an equality sign (=). The solution to a linear equation represents a specific line on a graph, while the solution to a linear inequality represents a region of the graph, typically shaded to show all the points satisfying the inequality. Moreover, linear inequalities allow for a range of values, whereas linear equations specify exact values for the variables.
If the slopes are the same on both graphs, they are parallel, and will never touch.
Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
There are many simple questions in everyday life that can be modelled by linear equations and solved using linear programming.
They are not. An inequality cannot, by definition, be the same as an equation.
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.
Linear equations or inequalities describe points x y that lie on a circle.
YES, all linear equations have x-intercepts. because of the x, y has to be there 2!
Descartes made the coordinate plane.
No. A linear graph has the same slope anywhere.
Rene Descartes was a French mathematician who created the coordinate plane on which linear equations are plotted.
Normally no. But technically, it is possible if the two linear equations are identical.
they express linear equations in a visible way
the equation graphs
Equations are never parallel, but their graphs may be. -- Write both equations in "standard" form [ y = mx + b ] -- The graphs of the two equations are parallel if 'm' is the same number in both of them.
