What is 3x 2y equals 16 in slope intercept form?
If you mean: 3x+2y = 16 then it is y = -1.5x+8
Can anyone solve x plus 2y equals 8 and 3x-2y equals 8 as a simultaneous equation and show their working?
x+2y=8 Here you must add the expressions (2y - 2y = 0) 3x-2y=8 4x=16 Now you are left with a multiple of x so you can simply divide by 4 x=4 on both sides of the = 4+2y=8 Now you substitute x=4 into one of the original equations to find y 2y=4 y=2 Hope this helped.
Slope of 2y equals 6x plus 8?
The slope is 3. --------------------- 2y = 6x +8 /2 /2 /2 y = 3x + 4 Now that it's in y = mx + b form, m = slope, m= 3
What are the solutions for the equations x equals 4y and 3x-2y equals 20?
x = 4y 3x - 2y = 20 Substituting the value of x into the second equation, 3*(4y) - 2y = 20 ie 12y - 2y = 20 or 10y = 20 so that y = 2 Then x = 4y = 4*2 = 8. So (x , y) = (8 , 2)
What does 6x plus 2y equals 8 look like on a graph?
A Straight line !!!! 6x + 2y = 8 Algebriacally rearrange 2y = -6x + 8 y = -3x + 4 It is now in the straight line form of y = mx + c , The gradient'slope is '-3' and the y-intercept is '+4'.
