-4x + 3y = 9

The given equation is y = x - 4x + 2 which can be written as y = -3x + 2 This is an equation of a straight line. Therefore it has no vertex and so cannot be written in vertex form.

3y = 4x + 9 -4x + 3y = 9 is the standard form

y = (11-4x)/5

y=4x+2

x^2+4x+7

4x-y+7=0

4x-14

2

y=-x^2+4x-3

In standard form it is 4x - 4y = 6 or 2x - 2y = 3

3y=4x+9.....-4xAnswer: 4x-3y=9

4x + y = 10 is a perfectly valid functional form. The standard form is 4x + y - 10 = 0

The answer to the problem of 13 equals -4x plus 9 is x equals -1.

8+4x

y= -4x + 10 Slope intercept form is y=mx+b

4x+2y = 20 2y = -4x+20 y = -2x+10

The standard form, which is the form that can be generalised to 3 or more dimensional spaces, is 4x + 5y - 13 = 0

4x plus 7 plus 3x equals 19 plus xx = 2

-4x + 4y = 1

4x+3y = 12 3y = -4x+12 y = -4/3x+4

It is: y = -0.4x+1 when in slope intercept form.

4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x

It is (1, 1).
