Answer:
Step-by-step explanation:
.
m is the slope of the line. To find it we can do 
which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So: 
. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant 
.
- Re-arranging to get b
Now re-write the equation as we have the constants.
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)
The answer is B.98
180-122=58
58+24=82
180-82=98
Hope it helped
