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.

What type of lines are these x plus 2y equals 7 and 2x plus 4y equals 21?
They are parallel lines.
What type of lines are these y equals 2x plus 4 and 12 equals 2y plus x?
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
Are lines parallel y equals 2x plus 7 and y equals 2x-7?
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 plus 3x equals?
2x+3x = 5x
If 5xequals 9plus 2x then x equals?
If 5 x equals 9 plus 2x then x equals?
What type of lines are these x plus 2y equals 7 and 2x plus 4y equals 21?
They are parallel lines.
What type of lines are these y equals 2x plus 4 and x plus 2y equals 12?
They are straight lines.
Which type of lines are 4x plus 6y equals 12 and 2x plus 3y equals -6?
They are parallel lines.
What type of lines are these y equals 2x plus 4 and 2y equals -4 plus 10?
parallel
What type of lines are these y equals 2x and y equals 4x plus 2?
neither
What type of lines are these y equals 2x plus 4 and 12 equals 2y plus x?
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
What type of lines are these y equals 2x and y equals 2x-1?
They are parallel lines
Do y equals 2x-1 and y equals 2x plus 1 have the same lines?
The lines are parallel, but not the same.
What type of lines are these y equals 2x and y-2x equals 3?
parallel
What are lines given by the equations y equals 2x and y equals 2x plus 1?
They are parallel.
Which type of lines are these y equals 2x and y equals 2x-1?
They are parallel lines with a vertical separation of 1.
What type of line is x plus 2y plus 6 and 4y equals 2x-12?
It is not one, but they are two perpendicular lines.
