The points (-3,-1) and (-3,5) are adjacent vertices of a rectangle. Two of the sides of the rectangle have a length of 8 units.

taurus [48]

Answer:

The answer to your question is 10 units

Step-by-step explanation:

Data

A (-3, -1)

B (-3 , 5)

length of a side = 8 units

Process

1.- Calculate the distance between A and B

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

x1 = -3 y1 = -1

x2 = -3 y2 = 5

-Substitution

dAB = $\sqrt{(-3 + 3)^{2}+ (5 + 1)^{2}}$

dAB = $\sqrt{0^{2} + 6^{2}}$

dAB = $\sqrt{36}$

dAB = 6 u

2.- Calculate the diagonal using the Pythagorean theorem.

c² = a² + b²

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = 10 units

- Conclusion

The diagonal of the rectangle measures 10 units

What is the answer to

Annette [7]

Answer:

y = 2/3x - 13

Step-by-step explanation:

We have a slope of 2/3 and a point (9, -7)

The point slope form of a line is

y-y1 = m(x-x1)

y--7 = 2/3 (x-9)

Distribute

y+7 = 2/3x - 6

Subtract 7 from each side

y+7-7 = 2/3x -6-7

y = 2/3x - 13

This is in slope intercept form.
