Q. The coordinates of the point J are (0,−10) and the coordinates of point K are (7,−10). What is the distance, in units, between the point J and point K?Answer: □ units
Identify Coordinates: Identify the coordinates of points J and K. Point J has coordinates (0,−10) and point K has coordinates (7,−10). We can see that the y-coordinates are the same, which means that J and K lie on a horizontal line.
Use Distance Formula: Use the distance formula for points on a horizontal line.The distance between two points on a horizontal line is the absolute difference between their x-coordinates. The distance formula is ∣x2−x1∣.
Calculate Distance: Calculate the distance using the x-coordinates of J and K. The x-coordinate of J is 0 and the x-coordinate of K is 7. So the distance is ∣7−0∣=7.
Verify Calculation: Verify the calculation for any possible errors.The calculation is straightforward subtraction and taking the absolute value, which is correctly done. There are no math errors.
