If it is horitzontal, the slope will be 0
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
(10,0) and (20,0)
slope=(0-0)/(20-10)=0/10=0
slope is 0
it is horzontal
or we could just recognize that the equation is y=0
Answer:
C) x = -

Step-by-step explanation:
Answer:
(3, - 25 )
Step-by-step explanation:
Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
The the x- coordinate of the turning point is
x = - 
Given
y = (x + 2)(x - 8) ← expand factors using FOIL
= x² - 6x - 16 ← in standard form
with a = 1 and b = - 6, thus
x = -
= 3
Substitute x = 3 into the equation for corresponding value of y
y = (3 + 2)(3 - 8) = 5(- 5) = - 25
turning point at (3, - 25 )
