The equation of the line that goes through the points ( − 3 , − 9 ) and ( − 6 , − 3 ) can be written in the form y = m x + b
ivolga24 [154]

Answer:

y=-2x-15

Step-by-step explanation:

y=mx+b.

m is the slope of the line. To find it we can do \frac{dy}{dx} which is the difference between the y-coordinates divided by the difference between the x-coordinates.

So: \frac{dy}{dx} =\frac{-9-(-3)}{-3-(-6)} =\frac{-6}{3} =-2. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant b.

-9=-2(-3)+b

b=-15 - Re-arranging to get b

Now re-write the equation as we have the constants.

y=-2x-15

Solve the equation p^2 + 4p = 1 by completing the square.
igor_vitrenko [27]

Answer:

p = -2 ±sqrt( 5)

Step-by-step explanation:

p^2 + 4p = 1

Take the coefficient of p

4

Divide by 2

4/2 =2

Square it

2^2 = 4

Add it to each side

p^2 + 4p+4 = 1+4

(p+2) ^2 = 5

Take the square root of each side

sqrt((p+2) ^2) =±sqrt( 5)

p+2 = ±sqrt( 5)

Subtract 2 from each side

p+2-2 = -2 ±sqrt( 5)

p = -2 ±sqrt( 5)
