If you mean y = 9/2x +9 then it is a straight line equation that can be simplified to y = 4.5x +9
The [ 2x + 1 ] represents a function of 'y' .
2 plus 1-x divided by.
Yes.
Because all the terms have been divided by -1
Yes.
Yes.
it equals 13X.
If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
Y = 2X + 8 is a linear function of the form, Y = mX + c. A line.
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
The rate of change for the linear (not liner) function, y = 2x +/- 3 is 2.
