x + 2y = 7
2y = -x + 7
y = -(x-7)/2 => -x/2 + 7/2
2x - y = 7
-y = -2x + 7
y = 2x + 7
Since -1/2 is the negative reciporical of 2, the slopes of these equations are perpendicular. Therefore, these two lines are perpendicular.
They are parallel lines.
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
Because the slope of these lines are the same, they are parallel. One crosses the y-axis at 7 and the other at -7. When written in this manner the number in front of the x is the slope.
2x+3x = 5x
If 5 x equals 9 plus 2x then x equals?
They are parallel lines.
They are parallel lines.
They are straight lines.
parallel
neither
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
They are parallel lines
The lines are parallel, but not the same.
parallel
They are parallel.
They are parallel lines with a vertical separation of 1.
It is not one, but they are two perpendicular lines.
