Answer:
Step-by-step explanation:
In standard form , any point the line passes through will make the inequality true. We can simply use any point given to find the equation of the line:
We can write the following system of equations from two points from the table:
Solving, we get:
For ,
Therefore, our equation is:
.
15 = 18 - 3 and 15 + 3 = 11 + 7 are true
(-1,0)
Convert the equation to vertex form which becomes y=(x+1)^2+0
Then we can see the vertex in the form (h,k) in y=a(x-h)^2+k
5 and 4
