Determine whether the given point (2,-2) lies on the line 3x-y=4 yes or no?

No

Step-by-step explanation:

For this problem you would solve for either x or y.  Since it is easier to solve for y, I will do so in this problem.  I multiplied both sides by -1 so that I can get rid of the negative sign on the left side of the equation

Now, we plug in 2 for x since they gave us (2, -2).

From this we can see that (2, -2) does not lie on the line since the problem gave us 2 and not -2.

Hope this helps <3

To determine whether the point is on the line, substitute/plug in either the x-value or the y-value of the point into the equation to see if it equals out:

3x - y = 4    I will use the x-value of the point, 2.

3(2) - y = 4

6 - y = 4   To find the value of "y", isolate/get the variable "y" by itself in the equation. Subtract 6 on both sides

6 - 6 - y = 4 - 6

-y = -2    Divide -1 on both sides to get "y" by itself

y = 2     >     (2, 2)

No, this point is not on the line because when x is 2, y equals 2 not -2.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
