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