Answer:
In an equation y = a(x - h) + k, the axis of symmetry will be x = h. This is because (h, k) is the vertex, and the parabola will be symmetric on both sides of the vertex.
Answer:
(-8, 15)
Step-by-step explanation:
Start by solving for y:
y=-x+7
Substitute -8 for x
y=-(-8)+7
The two negatives make a positive giving us:
y=8+7=15
Therefore...
(x,y)=(-8,15)
