Blue is not a solution.
(10, 2)
x = 12 y = 2 (12,2) satifies the equation
Any number that's two or less.
The ordered pair is (1, 3).
2x - 2y8 is an expression. It is not an equation and so cannot have a solution.
2x - 5y8 is an expression. It is not an equation and so cannot have a solution.
There are an infinite number of ordered pairs. (-5, -7) is one pair
-2,4
The equation 2x-5y=-1 has a graph that is a line. Every point on that line is an ordered pair that is a solution to the equation. So pick any real number x and plug it in. You will find a y and that pair (x,y) is an ordered pair that is a solution to this equation. For example, let x=0 Then we have -5y=-1so y=1/5 The ordered pair (0, 1/5) is a point on the line and a solution to the equation.
2 is a solution of the equation, but not if it's an inequality.
(-4,-5)
Blue is not a solution.
(10, 2)
x = 12 y = 2 (12,2) satifies the equation
y=(-1) x=(2)
