Answer:

[tex]\huge\boxed{\texttt{Yes. Explanation for why.}}[/tex]

Step-by-step explanation:

If we have the equation [tex]y = \frac{1}{2}x - 4[/tex] and we want to test if the point (4,–2) satisfies the equation, we can plug the x and y values into the equation and see if they make the equation true.

4 is the x value, -2 is the y.

[tex]-2 = (\frac{1}{2}\cdot4)-4[/tex]

[tex]-2 = 2 - 4[/tex]

[tex]-2 = -2[/tex]

So this does satisfy the equation.

Hope this helped!

Answer: this is really simple so we know that the coordinate points have an X and a Y value we see that (4,-2)

Step-by-step explanation:

We just plug it in for example

-2 for Y because it’s the Y value and 4 for x because it’s the X value

-2=1/2(4)-4

*we know that half of 4 is 2*

now the equation is -2=2-4

finally we just subtract 2-4 which is -2

-2=-2 so the equation is right
