x = 6
So y = 9*6 + 4 = 54 + 4 = 58
The ordered pair is (6, 58)
(0, 6)
-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)
it equals 13X.
The slope is 0.
There are infinitely many ordered pairs - each pair representing a different point on the infinite line described by the equation.
(0, 6)
x = 2, y = 3
-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)
You zero out the variables in turn. Y = 9(0) + 5 Y = 5 ---------- 9X + 5 = 0 9X = - 5 X = - 5/9 Can use these points to graph line. ( - 5/9, 5)
it equals 13X.
The slope is 0.
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
There are infinitely many ordered pairs - each pair representing a different point on the infinite line described by the equation.
9x - 2y = 73 . . . . . (a) 5x - 9y = 9 . . . . . (b) (a)*9: 81x - 18y = 657 (b)*2: 10x - 18y = 18 Subtract: 71x = 639 so x = 9 Substitute in (a): 81 - 2y = 73 2y = 8 so y = 4 The ordered pair is (9, 4)

It is 9x
9x + 9 = 135 9x = 126 x = 14
