It is a linear equation in two variables representing a line in the Cartesian plane.
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
6x+3y = -9 3y = -6x-9 y = -2x-3 Therefore the perpendicular slope is 1/2
Put in function, Y = mX + C, form. 6X + 3Y = - 9 3Y = - 6X - 9 Y = - 2X - 3 -------------------- m(slope) = - 2 ----------------------
Ok, sure. So:6x-3y-9=0-3y-9=-6x+0-3y=-6x+9y=2x-3
6x + 3y = -9 So 3y = -6x - 9 or y = -2x - 3 So the slope of the given line is -2 Therefore, the slope a any parallel line is also -2.
(x, y) = (3, 7) is a solution.
-4x + 3y = 9
-6x + y = 9 (+6x) -> y = 6x + 9
3y = 4x + 9 -4x + 3y = 9 is the standard form
-6x+9 = 45 -6x = 45-9 -6x = 36 x = -6
16x+9 without the rest of the equation, what this equals, I can't solve
3y=4x+9.....-4xAnswer: 4x-3y=9
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
