Put in function form.
- 2X + 2Y = 4
2Y = 2X + 4
Y = X + 2
-------------set to 0
X + 2 = 0
X = -2
--------------X intercept
2x-y=4
y = -2x+10
y = 2x + 3
2y = 2x + 8Divide each side by 2:y = x + 4The slope is 1.The y-intercept is 4.
4x+2y = 20 2y = -4x+20 y = -2x+10
4x + 2y = -8 → 2y = -4x - 8 → y = -2x - 4
6
4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2
-3x + 2y = 8To get into slope intercept, we must set the equation equal to y2y = 3x + 8y = 3/2x + 8/2y = 3/2x + 4
-x+2y = 6 2y = x+6 y = 1/2x+3 Therefore the slope is 1/2 and the y intercept is 3
-2X + 2Y = 4 2Y = 2X + 4 Y = X +2 by inspection, 2 but, you could also 0 out X in original equation -2(0) + 2Y = 4 2Y = 4 Y = 2
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
