Answer:

12a. (-6, -6)

12b. 17

13a. y = $\frac{-1}{2}$ x + $\frac{3}{2}$

13b. 2

Step-by-step explanation:

12a. Using the midpoint formula:

$(\frac{-9-3}{2} ,\frac{2-14}{2} )$ = $(\frac{-12}{2} , \frac{-12}{2})$ = (-6, -6)

12b. Using the Distance formula:

d = $\sqrt{(3 - (-9))^{2} +( 14 - 2)^{2} }$ = $\sqrt{(12)^{2}+(12)^{2} }$ = $\sqrt{144 + 144}$ = $\sqrt{288}$

= 12 $\sqrt{2}$ or 17

13a. x + 2y = 3

2y = 3 - x

y = $\frac{-1}{2}$ x + $\frac{3}{2}$

13b. The perpendicular slope is 2

You would have to change it into an improper fraction which you would just subtract 14 from the numerator

Find the distance between the points given. (-1, -1) and (1, 3) √5 √(17) 2√5

Pani-rosa [81]

Answer:

2√5

Step-by-step explanation:

d = √(x2 - x1)² + (y2 - y1)²

= √[1 - (-1)]² + [3 - (-1)]

= √(2)² + (4)²

= √(4) + (16)

= √20

= 2√5
