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.

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 does slopes of parallel and perpendicular mean?

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.


What equations a line parallel to the line given by y equals 5x plus 9?

It will be any of the equations that has the same slope of y = 5x+9 but with a different y intercept


What equations represents a line parallel to the line given by y equals 5x plus 9?

The equations will have the same slope as y = 5x+9 but a different y intercept


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



If x equals equals 9 how many would 5x be worth?

If X = 9 then 5X would = 5 x 9, which is 45.


What is the answer to 39 equals 5x plus 9?

39 = 5x + 9 5x = 39 - 9 5x = 30 x = 30 / 5 x = 6


Y equals 5x plus 18 y equals 2x plus 9?

5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3


-7 plus 11x equals 9-5x?

-7+11x = 9-5x 11x+5x = 9+7 16x = 16 x = 1


How do you write multiplication problems in algebra?

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

What is the equation to a line that is perpendicular to the graph of 5 x minus 3 y equals 9 and the two lines intersect at x equals 15?

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



What is the solution 5x-9 equals 4x?

What is 5x plus 9 equals 3x 15?

if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3


How do you solve 5x plus 9 equals 4?

5x + 9 = 4Subtract 9 from each side:5x = -5Divide each side by 5:x = -1
