Vx = axis of symmetry
Vx=-b/2a
b=4 and a=1
Vx=-4/2
Vx=-2
therefore, the AOS is x= -2
The equation is y= -2x + 1
The answer to this is A. I hope this helps
Step by step explanation:
9
+6x+5=0
Uses the "a", "b", and "c" from "a
+ bx + c", where "a", "b", and "c" are numbers
So in this case:
a would be 9
b would be 6
c would be 5
Then plug in from there..
Another way you can do it is using the square method.
The line x = 2 is perpendicular to the x-axis.
That is to say it is vertical and it’s slope is undefined.
Line l must be horizontal so it has a slope of 0
