5x-4y=8
If you mean: y=-5x+10 and the point (3, 10) then the parallel equation is y=-5x+25
The slope is 5. Parallel lines always have the same slope.
The equations will have the same slope as y = 5x+9 but a different y intercept
Convert the equation 2y = 5x - 4 into standard form then y = 2.5x - 2. Two straight lines are perpendicular if the product of their gradients is -1. Let the equation of the perpendicular line by y = mx + b. Then, 2.5m = -1 : m = -1/2.5 The y intercept occurs when x = 0. Then -3 = 0 + bc : b = -3 The equation of the perpendicular line is y = -1/2.5x -3 or 5y = -2x -15
If they have the same slope, they are parallel. The slopes are the same, so yes they are parallel.
y5x-1y5x=1y=1/5xTherefore the gradient is 1/5x
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.
y=5x-3
If you mean 5x+y = 21 and x = 6-2y then x = 4 and y = 1
If you mean y = 5x-13 then in standard form it is 5x-y-13 = 0
When two lines are parallel, they have the same slope. For example:y=5x-3 andy=5x+9These lines are parallel, because they have the same slope.When two lines are perpendicular they have negative reciprocal slopes. For example:y=2x-6 andy=-1/2x+2These lines are parallel, because they have negative or opposite reciprocal slopes.
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.

If you mean y = 5x-3 then it is the linear equation of a straight line
