- 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
To solve the equation 9x + y = 22, you need to isolate one of the variables. You can do this by either substituting a value for one variable and solving for the other, or by rearranging the equation to solve for one variable in terms of the other. For example, if you choose to solve for y, you would subtract 9x from both sides to get y = 22 - 9x. If you choose to solve for x, you would subtract y from both sides to get 9x = 22 - y, then divide by 9 to solve for x.
