Certainly not parallel and probably perpendicular but it is not possible to be sure of that because limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a categoric answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc.

Write an equation of a line parallel to 5x-4y equals 8?

5x-4y=8


Which is the slope of a line parallel to the line 5X-4y equals 9?

To answer this question we need to first get the slope of the line 5x-4y=9 by rearranging it in the form of y=mx+b: 5x-4y=9 4y=5x-9 y=(5/4)x-9/4 Since the slope of parallel lines are negative reciprocals of each other, the negative reciprocal of 5/4 is -4/5, therefore the slope of a line parallel to the line 5x-4y=9 is -4/5


Is 5x 2y9 and 5x 2y2 parallel perpendicular or neither?

If they have the same slope, they are parallel. The slopes are the same, so yes they are parallel.


Is y equals -5x 9 parallel or 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.


-2x-4y plus 5x-7y equals?

Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y


Slope of 5x plus 4y equals 20?

5x + 4y = 204y = -5x + 20y = (-5/4)x + 5


What is the x-intercept and y-intercept of 5x subtract 4y equals 1?

y-intercept: -1/4 x-intercept: 1/5 5x-4y=1 -4y=-5x+1 y=5/4x+1/-4 5x-4y=1 5x=4y+1 x=4/5y+1/5


Are y-5x 9 and 5x y-21 parallel or perpendicular?

In the absence of equality signs it's difficult to say but in general if the slope remains the same and the y intercept differs then they are parallel


What is 2x plus 4y-5x plus 3y?

2x + 4y - 5x + 3y = 7y - 3x


What is the slope of the equation 5x plus 4y equals negative 3?

5x+4y = -3 4y = -5x-3 y = -5/4 x - 3 Slope is -5/4.


What is the y-intercept for 5x-4y equals 18?

Transform the equation into slope-intercept form: y = mx + b. The intercept is b. 5x - 4y = 18 -4y = 18 - 5x 4y = 5x - 18 y = 5x/4 - 18/4 so the y-intercept is -18/4 or -4.5


What is 5x-4y-28?

It is an algebraic expression but if you mean 5x-4y-28 = 0 then it is a straight line equation.
