To set up the distance formula correctly for the points L(4, 2) and M(7, 6), we will use the distance formula, which is given by:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
Here, \( (x_1, y_1) \) are the coordinates of point L and \( (x_2, y_2) \) are the coordinates of point M.
For the points L(4, 2) and M(7, 6):
- \( x_1 = 4 \), \( y_1 = 2 \)
- \( x_2 = 7 \), \( y_2 = 6 \)
Using the distance formula:
\[ d = \sqrt{(7 - 4)^2 + (6 - 2)^2} \]
This simplifies to:
\[ d = \sqrt{(3)^2 + (4)^2} \]
None of the provided responses are the exact distance formula in this case, with the correct substitution of coordinates. However, the correct setup should start with \( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \).
To look at the options given:
- \( d = \sqrt{(2 - 4)^2 + (6 - 7)^2} \) → This one is incorrect.
- \( d = \sqrt{(4 - 7)^2 + (2 - 6)^2} \) → This one is actually correct since it gives the distance in the same effective way.
- \( d = \sqrt{(2 - 7)^2 + (4 - 6)^2} \) → This one is incorrect.
- \( d = \sqrt{(6 - 7)^2 + (2 - 4)^2} \) → This one is incorrect.
The correct choice is:
d = \sqrt{(4 - 7)^2 + (2 - 6)^2}
This reflects the proper calculation of distance between the points.
