Answer:
Graph #2
Step-by-step explanation:
I would use Desmos for this, makes it easier to find out which graph is for the equation.
Answer:
The coordinates of point C are (a,0).
Step-by-step explanation:
Given information: ABC is right isosceles triangle.
From the given figure it is noticed that the side BC is hypotenuse of the triangle ABC.
By pythagoras theorem,



Therefore hypotenuse cannot be equal to leg. So, we can say that in triangle ABC,

Length of AB is

From the figure it is noticed that the point C lies on the x-axis, therefore the y-coordinates of C is 0.
Let the coordinates of C be (x,0) and length of AC must be a.


Therefore coordinates of point C are (a,0).
P = 2a + b + c
Subtract 2a + b on both sides
c = P - (2a+b)
c = P - 2a - b
