- 9X + 3Y = - 6 add 9X to each side 3Y = 9X - 6 divide all by 3 Y = 3X - 2
-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)
Well, if you solve the equation for "y", you have "y" as a function of "x". Or you can do it the other way round; solve for "x", to get "x" as a function of "y" (the first option is more commonly used, though).
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
If you mean 9x-2y = 6 then it is a straight line equation that can be expressed as y = 4.5x-3 whereas 4.5 is the slope and -3 is the y intercept.

The inverse of an equation is rewriting it as a function of the other variable. Simply solve the equation for x instead of y. y=9x can be written as x= (1/9)y --> fy=y/9◄ y=4x+6 (or 4x+6=y) -> 4x=y-6 -> x=(y-6)/4 --> gy=(y-6)/4■

The inverse of the function y = 9x is x/9.
If: 9x-2y = 14 Then: y = 4.5x-7 in slope intercept form
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
If you mean 9x-2y = 6 then it is a straight line equation that can be expressed as y = 4.5x-3 whereas 4.5 is the slope and -3 is the y intercept.
2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2
9x + y = 22to solve for x-subtracy y from both sides --> 9x = 22 - ydivide by 9 on both sides --> x = (22/9) - (y/9)to solve for y - subtract 9x from both sides --> y = 22 - 9x
