Asap 15 points find the slope of the line which goes through the given points. 1.) a(2,4) and b(4,9) 2.) c(12,3) and d(12,4) 3.)a(2,8) and b(2,6) 4.)a(−8, 12) and b(0,2) 5.) a(5,8) and b(2,8)

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

square root

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
