What is the slope of the line whose equation 6x plus 3y equals 18?
6x+3y = 18 3y = -6x+18 y = -2x+6 Therefore the slope is -2 and the y intercept is 6
What is the slope of the line determined by the equation 6x -3y 18?
This is not an equation because there's no equal sign If you mean: 6x -3y = 18 Then -3y = -6x+18 And: y = 2x-6 So the slope is 2 and the y intercept is -6
What is the answer of -6x equals 6y plus 6 and -6x equals 3y -12?
-6x = 6y + 6 -6x = 3y - 12 Subtracting the second from the first gives: -6x - -6x = 6y - 3y + 6 - -12 → 0 = 3y + 18 → 3y = -18 → y = -6 Substituting in the first: -6x = 6y + 6 → -6x = 6(-6) + 6 → -6x = -36 + 6 → -6x = -30 → x = 5 Thus x = 5, y = -3 solve the simultaneous equations.
Rewite in slope intercept form 6x-3y-9 equals 0?
Ok, sure. So:6x-3y-9=0-3y-9=-6x+0-3y=-6x+9y=2x-3
What is -6x plus 3y equals -18 -10 plus 5y equals -30 using substitution?
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4
