coordinate geometry – straight lines - The lines p and q meet the y-axis at the points A (0, \frac{22}{2}) and B (0, -7) respectively. Find the distance between AB.

Step 1: Locate the coordinates of the endpoints.

EXAMPLE: The two endpoints M (2, 1) and N (6, 4). Therefore, (x_1, y_1) =

(2, 1) and (x_2, y_2) = (6, 4).

Step 2: Plug the corresponding coordinates into the Distance Formula. .

FORMULA:

d = \sqrt{(x_2 - x_2)^2 + (y_2 -y_1)^2}

EXAMPLE: Endpoints M (2, 1) and N (6, 4).

d = \sqrt{(6 - 2)^2 + (4 - 1)^2}

Step 3: Calculate the subtraction in parentheses.

Step 4: Square the value in parentheses.

Step 5: Add the numbers under the radical sign.
