Does the point (3,4) lie on the line 5x - 2y = 6?

Question

please show me how you got to the conclusion.

Answer 1

5*(3) - 2*(4) = 15-8=7 So... NO (3,4) does not lie on the line.

Answer 2

Substitute x=3 and y=4 in this equation

5 x 3 - 2 x 4
=15 -8
= 7 , which is not equal to 6.

So the point doesn't lie on that line

Answer 3

No,

In order to verify if a certain vlaue lie in a givne line it is possible to dsubstitute the value int he equation. Considerign the given point:

(x,y)=(3,4)

5x-2y=5*(3)-2*(4)=15-8=7 which is different than "=6"

Therefore the point does not lie in the givne line.

I hope it going to help

Answer 4

Just substitute the variables by the point's coordinates:

5x - 2y = 6
5 * 3 - 2 * 4 = 6
15 - 8 = 6
7 = 6

Oops, values don't match; then, (3, 4) isn't in 5x - 2y = 6.

Answer 5

No it doesn't!

5x - 2y X=3 Y=4
=5(3) - 2(4)
=15 - 8
=7

this shows that 5x - 2y does not = 6

Answer 6

this equation is a function, like a little machine that will give you values for y when you put in different values for x. if you want to see whether the point (3,4) lies on the line, you just put in 3 for x, and see whether 4 comes out for y.

5(3) - 2y = 6

subtract 6 from both sides and add 2y to both sides for:

9 = 2y

now divide both sides by 2 and you get y = 9/2

which is 4.5, not 4. so the answer is no.

Answer 7

Just sub in the values and see if it holds true. 5*3 - 2*4 = 15 - 8 = 7, not 6, so (3,4) is not on the line.

Answer 8

Just substitute into the equation and see if it is true.

since x = 3 and y =4, the equation is 5*3 - 2*4 = 7 which IS NOT 6 therefore the given point DOES NOT fall on the line lgiven.

Answer 9

No

Plug the values into the equation that you're given.

5(3) - 2(4) = 6
15 - 8 = 6
7 ≠ 6

Answer 10

Just plug in 3 for x and 4 for y:
5(3) - 2(4) = 6
15 - 8 = 6
That's not true, so the point is not on the line.
