The solution to a system of linear equations in two variables is any ordered pair (x,y) that satisfies each equation independently. Graphically, solutions are points at which the lines intersect.

Is 2x y 4 linear?

Yes, it is a linear equation.

What is the Y-intercept of 4x 2y =- 8?

Using the slope-intercept form, the y-intercept is −4 .

How many solutions does this linear system have?

A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

How many solutions does this linear system have y 2x 5 8x 4y 20?

one solution
The linear system y = 2x – 5 and -8x – 4y = -20 has only one solution.

What is the standard form of Y 2x?

Algebra Examples The standard form of a linear equation is Ax+By=C A x + B y = C . Rewrite the equation with the sides flipped. Subtract y from both sides of the equation.

How do you solve 4x + 2y = 8?

Substitute − 2 3 y ​ for x in the other equation, 4 x + 2 y = 8. Multiply 4 times -\\frac {3y} {2}. Multiply 4 times − 2 3 y ​. Add -6y to 2y. Add − 6 y to 2 y. Divide both sides by -4. Divide both sides by − 4. Substitute -2 for y in x=-\\frac {3} {2}y. Because the resulting equation contains only one variable, you can solve for x directly.

How to solve multiply – 2 3 times – 2?

Multiply − 2 3 ​ times − 2. The system is now solved. The system is now solved. 2x-y=4;x+2y=7 Solution : {x,y} = {3,2} System of Linear Equations entered : [1] 2x – y = 4 [2] x + 2y = 7 Graphic Representation of the Equations : y + 2x = 4 2y + x = 7 Solve by Substitution :

How do you subtract -8x-4y=-16 from -8x-12y=0?

Subtract -8x-4y=-16 from -8x-12y=0 by subtracting like terms on each side of the equal sign. Add -8x to 8x. Terms -8x and 8x cancel out, leaving an equation with only one variable that can be solved.
