-9x+6=y (swap over +6 and y)
-9x-y=-6 (when u move numbers or letters over d equal sign u need 2 change signs)
9x+y=6 (chaned all signs)
y= 6-9
y= -3
9x+y=6
9x+-3=6
9x=6+3
9x=9
x=9(divided by) 9
x=1
9x+y=6
9+-3=6
So the ordered pair is (1,-3)
(0, 6)

There are infinitely many ordered pairs: each point on the straight line defined by the equation is an ordered pair that is a solution. One example is (0.5, 2.5)
There are an infinite number of ordered pairs. Any point on the straight line which passes through (0,4) and has a gradient of -2 will be an ordered pair for the equation.
(4.25, 0.25) is a solution.

There are infinitely many ordered pairs: each point on the straight line defined by the equation is an ordered pair that is a solution. One example is (0.5, 2.5)
There are an infinite number of ordered pairs that satisfy the equation.
x = 5 and y = 4
x = 2 and y = -4
x = 12 y = 2 (12,2) satifies the equation
There are an infinite number of ordered pairs. Any point on the straight line which passes through (0,4) and has a gradient of -2 will be an ordered pair for the equation.
(4.25, 0.25) is a solution.
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.
(0, 6.5) is one option.
