Choose the point-slope form of the equation below that represents the line that passes through the points (−6, 4) and (2, 0). (2 points) a. y − 4 = − one half(x + 6) b. y − 4 = 2(x + 6) c. y + 6 = − one half(x − 4) d. y + 6 = 2(x − 4)

A: y-4=-1/2(x+6)

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

slope = (0-4)/(2+6)

slope = -4/8

slope = -1/2

passes through the points (−6, 4)  

y - 4 = -1/2(x + 6)

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
