Answer:
You will need to draw this out yourself.
Explanation:
But to map each point, you find the x (left or right) then y (go up or down).
For example, point A is -1,7
so move one block to the left is -1, move your finger up 7 (line inbetween 6 and 8) that is point A.
Draw for all the others, connect each group of three points to draw the triangle
