The equation for the following graph:

Step-by-step explanation:

- You first need to find the slope by using the slope formula:

(where is the first point and is the second point)

-Use the given points and from the graph for the formula:

Then, you solve:

After you have found the slope, use the slope and the first point for the point-slope formula:

(where is the slope and is the first point)

Then, you solve:

So, the equation for the following graph is .

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
