Neither perpendicular nor parallel

Neither: because one line, by itself, can be neither parallel or perpendicular. These characteristics are relevant only in the context of another line (or lines). The given line is parallel to some lines and perpendicular to others.

They are both parallel because the slope or gradient is the same but the y intercept is different.

If the second equation is: y minus 2x equals 3, then:y - 2x = 3 ⇒ y = 2x + 3 and it is parallel to y = 2x.Otherwise (with with missing operator as "plus", "multiply" or "divide"), the lines are neither parallel nor perpendicular.

Parallel. They both have a slope of 4.

y=-2 is parallel to the x-axis and perpendicular to the y-axis.

No, they are perpendicular.

Base on the slope of two linear equations (form: y = mx+b, where slope is m): - If slopes are equal, the 2 graphs are parallel - If the product of two slopes equals to -1, the 2 graphs are perpendicular. If none of the above, then the 2 graphs are neither parallel nor perpendicular.

y = -5x + 9 is the equation of a straight line. It cannot be parallel or perpendicular by itself, you need another line to compare it to.

They are parallel because the slope has the same value in both equations.

They are perpendicular lines because the slopes are 3/4 and -4/3 respectively.

One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.

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

No. They are parallel.

All parallel lines have a zero slope.

y=2x-3 2x-4y=8-4y=-2x+8y=-2/-4x+8/-4y=1/2x-2the equation for slope intercept form is y=mx+bm being the slopeparallel equations would have the same slope (m) andperpendicular equations have opposite reciprocal slopesthe opposite reciprocal of 2 is -1/2the equations are neither parallel or perpendicular.

It depends on the line(s). Can you give us more information?

the answer in the text book is 0.693 but i cannot get the answer

[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.

if they are parallel they run side by side forever and will never cross. if they are perpendicular they will cross at a 90 degree angle. You can also tell just by looking at the equations for the lines if they are in the slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept). When two lines are parallel, they have the same slope. When two lines are perpendicular, the slope of one is the negative reciprocal of the slope of other. For example, a line with a slope of 2 is perpendicular to a line with a slope of -½, and a line with a slope of 1 is perpendicular to a line with a slope of -1. (y = 1 and x = 1 are perpendicular because the slope of y = 1 is zero, the slope of x = 1 is infinity, the reciprocal of infinity is zero, and negative zero equals zero.)

No. they are parallel, since the slopes are both equal in this case 3. To be perpendicular the product of the slopes of both lines is equal to -1 (i.e., m1*m2 = -1).

None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.
