X-intercept is -1 implies line passes through (-1,0).
So point slope form is
y - 0 = -2 (x -(-1) )
>> y = -2 (x +1) <----- FINAL ANSWER
Answer:
put -2 in -2 / put -2 again in same spot and again just do it for 3 times then 1/3 in the middle of 0 and -2 but a bit closer to the -2

Quadratic equation
![x=\frac{-b+-\sqrt{b^{2}-4*a*c} }{2*a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%2B-%5Csqrt%7Bb%5E%7B2%7D-4%2Aa%2Ac%7D%20%7D%7B2%2Aa%7D)
The discriminant is the part of the quadratic formula within the square root symbol:
. The discriminant indicates if there are two solutions, one solution, or none.
The discriminant can be positive, zero or negative which determines how roots exist for the given quadratic equation.
So, a positive discriminant tell us that the quadratic has two different real solutions.
A discriminant of zero tell us that the quadratic has two real and equal solutions.
And a negative discriminant tell us that none of the solutions are real numbers.
In this case: 25x^2-10x+1=0
We can see that
a= 25 b=-10 c=1
Using: ![{b^{2}-4*a*c}](https://tex.z-dn.net/?f=%7Bb%5E%7B2%7D-4%2Aa%2Ac%7D)
We have ![-10^{2}-4* 25*1 =100-100=0](https://tex.z-dn.net/?f=-10%5E%7B2%7D-4%2A%2025%2A1%20%3D100-100%3D0)
the answer is zero, so the quadratic has two real and equal solutions
Answer:
About Points
S = (x,y) searched point (it will be in the third quadrant )
M = (-2,0) Midpoint | SP |
P = (3,5) one end of the segment | SP |
You have to draw Cartesian.
we set in a point M and P. We both points by a simple and we extend it for the third quarter of the system. Compass measure the distance from the point M to the point P. From the point M we set a compass point S. Figure attached. Received point S = ( -7 , -5 ) . It sought a point that calculate .
We use the information that | SM | = | MP |
Answer : S = (-7,-5)
