Answer: (-1,0)

------------------------------------------------

Explanation:

A quick method is to simply look at the graph and notice the two altitudes cross at (-1,0)

----------

A longer method involves a bit of algebra but its not too bad

y = x+1
y = -1+1 ... plug in x = -1 (ie replace x with -1)
y = 0
So when x = -1, the value of y is y = 0
They pair up to get (x,y) = (-1,0) which confirms what the graph is showing

Answer:

Reflection

Step-by-step explanation:

It is reflecting across the Y axis. It is not a dialation, since it is the same shape, but not a different size. Its not rotation, because it wasnt rotated to get to the new shape. And it is not translation, because it is not exactly the same shape (the shape was mirrored)
