3y = 4x + 9 -4x + 3y = 9 is the standard form
It is a straight line equation that can be simplified to: y = 3x-9
-4x + 3y = 9
The equation for 3y + 3y = -1 is 3y + 3y = -1.
8x-3y=6-4x gives 12x-3y=6 which in standard form is y=-2+4x
(2/5)x + 3y = 10 Multiply through by 5: 2x + 15y = 50 That is the standard equation of a line in 2-dimensional coordinate geometry.
4x+3y = 3 3y = -4x+3 y = -4/3x+1 in slope intercept form
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
First rewrite the equation in the "standard" form: 3y = 5x + 8 so that y = 5/3*x + 8/3 Then the slope is the coefficient of x, ie 5/3 or 1.66...
A linear equation in standard form will be Ax + By = C or in some books Ax + By + C = 0 where A, B, and C are real numbers such as 3x + 3y = 18
