I hope this helps you

-4x-2y+4x+8y= -12-24

6y= -36

y= -6

-4x-2. (-6)= -12

-4x+12= -12

-4x= -24

x=6

(6, -6)

Explain the distance formula. Then use it to calculate the

Alex777 [14]

Answer:

$dAB=10\ units$

Step-by-step explanation:

we know that

The <u>distance formula</u> is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. The hypotenuse of the triangle is the distance between the two points

The formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$
