2y = 4x + 4y = 2x + 2

(-2, 4)

(4, -1)

x = 2y = 4

4x + 2y = -8 → 2y = -4x - 8 → y = -2x - 4

If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines

-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

They are straight lines.

2x-y=4

At the point (2, 4).

Solve for y: 2x+2y=8 2y=-2x+8 y=-x+4 f(x)=-x+4 I think that's what you mean.

The lines are mutually perpendicular.

Put in function form. - 2X + 2Y = 4 2Y = 2X + 4 Y = X + 2 -------------set to 0 X + 2 = 0 X = -2 --------------X intercept

x = 4 and y = -1 (4. -1)

x = -2 and y = 3

y=16 x= -4

The second equation works out as y = -1/2x+6 therefore it is perpendicular

This means that 2y - 3 = 2y + 4 which is not possible.

4x+2y-8=0 2y=8-4x y=4-2x slope= -2

2y = 2x + 8Divide each side by 2:y = x + 4The slope is 1.The y-intercept is 4.

3x + 2y = 4; 2x - 2y = 16 Add; 5x = 20 so x = 4 and y is therefore -4
