2x+4y = -8 4y = -2x-8 y = -1/2x-2 or y = -0.5x-2
x = 4 and y = 0
2x+4y=8 4y=-2x+8 y=-2/4x+2 M=-2/4 B=2 B=Y Intercept
2x - 4y = 8 2x = 4y + 8 x = 2y + 4
Convert the function into the general form y = mx + c, where 'm' is the slope. 2x + 4y = 8 : 4y = -2x + 8 : y = -x/2 + 2 : The slope is therefore -1/2.
2x+4y = -8 4y = -2x-8 y = -1/2x-2 or y = -0.5x-2
2x-4y=-8-2x......-2x-4y=-2x-8(-4y)/-4 | (-2x-8)/-4y=1/2x+2
x = 4 and y = 0
2x+4y=8 4y=-2x+8 y=-2/4x+2 M=-2/4 B=2 B=Y Intercept
2x - 4y = 8 2x = 4y + 8 x = 2y + 4
Convert the function into the general form y = mx + c, where 'm' is the slope. 2x + 4y = 8 : 4y = -2x + 8 : y = -x/2 + 2 : The slope is therefore -1/2.
2x + 4y = 16 <=> 2x + 4y - 16 = 0 2x - 4y = 0 2x - 4y = 2x + 4y - 16 -8y = -16 y = 2 Substituting the known value for y in either of the original equations enables x to be determined. 2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4 2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4. The ordered pair satisfying both equations is (4,2)
-2x +4y = 8 4y = 2x +8 y = 1/2x +2 Therefore: the y intercept is 2 and the slope is 1/2
You cannot solve one equation in two unknowns.
