So firstly, subtract x on both sides:
Next, divide -2 on both sides, and your answer will be y = 1/2x - 3/2 , or the last option.
Please consider the attached file.
We can see that triangle JKM is a right triangle, with right angle at M. Segment KM is 6 units and segment MJ is 3 units. We can also see that KJ is hypotenuse of right triangle.
We will use Pythagoras theorem to solve for KJ as:
Now we will take positive square root on both sides:
Therefore, the length of line segment KJ is and option D is the correct choice.
