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.
It will be any of the equations that has the same slope of y = 5x+9 but with a different y intercept
If X = 9 then 5X would = 5 x 9, which is 45.
39 = 5x + 9 5x = 39 - 9 5x = 30 x = 30 / 5 x = 6
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
y = 5x + 9

The equations will have the same slope as y = 5x+9 but a different y intercept
It will be any of the equations that has the same slope of y = 5x+9 but with a different y intercept
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
5x = 4x + 9 x = 9
If X = 9 then 5X would = 5 x 9, which is 45.
39 = 5x + 9 5x = 39 - 9 5x = 30 x = 30 / 5 x = 6
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
y = 5x + 9

For example 5x \ 9 x 5 + 10 + 72 = 9 So you move 72 over to 9 and minus it 5x / 9 x 5 + 10 = 9-72 Then bring 10 over 5x / 9 x 5 = -63- 10 Then brong 5 over 5x / 9 equals - 73 5x equals -73 times 9 5x equals 146 X equals to 146 divide by 5 Thanks you Hello Israel
It is 3x + 5y = 155 The slope of the line 5x -3y = 9: 5x - 3y = 9 → 3y = 5x - 9 → y = 5/3 x - 3 → slope is 5/3 → slope of perpendicular line is -3/5 Intercept at x = 15 → y = 5/3 x 15 - 3 = 22 → equation of perpendicular line is: y - 22 = -3/5 (x - 15) → 5y - 110 = -3x + 45 → 3x + 5y = 155
