Answer:
(-1/2, 23/4)
Step-by-step explanation:
Vertex of graph: -b/2a
b=1
a=1
Therefore, -1/2 is your x-value
Solve for y: y=1/4-1/2+6
y=5 3/4 or 23/4
Therefore your vertex is: (-1/2, 23/4)
Answer:
Equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
Step-by-step explanation:
General equation of slope intercept form : 
We are supposed to find equations in slope-intercept form for three different lines that intersect at (–2, 3).

Substitute the value in the general equation
y-3=m(x+2)
Now substitute any 3 values of m
At m = -1

At m =0

At m =1

They all intersect at the given point.
So, equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
ur gonna do : lxbxh
so :
