4x+2y = 20 2y = -4x+20 y = -2x+10
8x+2y=4x=-y/4+0.5y=-4x+2
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
-2
4x+2y = 6 2y = -4x+6 y = -2x+3 Slope = -2
2y = 4x + 4y = 2x + 2
Subtract first from second gives -4x = 16 so x = -4 and y = -7
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
4x+2y = 20 2y = -4x+20 y = -2x+10
8x+2y=4x=-y/4+0.5y=-4x+2
-4x-2y = 3 -2y = 4x+3 y = -2x-1.5 which is the equation of a straight line
what is the slope of the line that has the equation 4x+2y=12?
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
-2
4x+2y-8=0 2y=8-4x y=4-2x slope= -2
4x+2y = 6 2y = -4x+6 y = -2x+3 Slope = -2
No.
