(-1, 2)
2y = 4x + 4y = 2x + 2
4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
4x+2y = 20 2y = -4x+20 y = -2x+10
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
-4x-2y = 3 -2y = 4x+3 y = -2x-1.5 which is the equation of a straight line
4x-2y = 3 -2y = -4x+3 y = 2x-1.5 in slope intercept form
8x+2y=4x=-y/4+0.5y=-4x+2
4x+2y-8=0 2y=8-4x y=4-2x slope= -2
4x-2y = 10 -2y = -4x+10 y = 2x-5 which is now in slope-intercept form
4x-2y = 5 -2y = -4x+5 y = 2x-2.5 The slope is 2 and the y intercept is -2.5
