Question

SHOW FULL WORK FOR BRAINLY. make the answer actually make sense

Answer 1

Answer:

7

Step-by-step explanation:

To solve for this equation, we are going to use the distance formula, or what is known as:

$\sqrt{(x_{2} -x_{1})^{2}+ (y_{2} -y_{1})^{2} }$

Solving for distance is easier to do with perfect squares, in which this one is. If you're ever wondering which way to arrange the x2-x1 it doesn't matter how you put it, just be sure to put both x and y in the same order.

$\sqrt{(x_{2} -x_{1})^{2}+ (y_{2} -y_{1})^{2} } \\K(4,5)\\L(4, -2)\\\sqrt{(4 -4)^{2}+ (-2 -5)^{2} }\\\sqrt{(0)^{2}+ (-7)^{2} }\\\sqrt{(0)+ (49) }\\\sqrt{49} = 7$

I am happy to help with any other questions you might have in the future and I will continue to work hard in trying to provide the best answers I can :)

Answer 2

Answer:

B, 7 units.

Step-by-step explanation:

Since points K and L have the same x value, their only difference in location is with their y coordinate. The difference between the first y coordinate (5) and the second y coordinate (-2) is 5-(-2)=7 units, which is the length of KL. Hope this helps!
