Answer:
hope this helps buddy, please mark the brainliest.
Step-by-step explanation:
The mistake was in step one when she added the 9 to both sides
x^2 + 8x - 9 = 0
__ + __ = 8 (b)
__ • __ = -9 (a•c)
blanks = -1 and 9
(x - 1)(x + 9)
Solve for x in each one
x = 1 or -9
Answer:
I'd say your answer should be (B.) A and B
Step-by-step explanation:
point B on your graph is in quadrant one.
also, your point is at (5,4) so both numbers of your point are positive.
therefore, your answer should be (B.) A and B
Hope this helps!
The point-slope form:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
We have the point
and the slope
.
Substitute:
![y-2=\dfrac{1}{2}(x-(-8))\\\\\boxed{y-2=\dfrac{1}{2}(x+8)}](https://tex.z-dn.net/?f=y-2%3D%5Cdfrac%7B1%7D%7B2%7D%28x-%28-8%29%29%5C%5C%5C%5C%5Cboxed%7By-2%3D%5Cdfrac%7B1%7D%7B2%7D%28x%2B8%29%7D)
