Answer:
y=x-3
Step-by-step explanation:
slope intercept form is y=mx+b
b is y intercept
so we plug the coordinate into the equation
-3=(0)+b
-3=b
so y intercept is -3
so we then write our equation which is,
y=x-3
Answer:
The coordinates are and
.
Step-by-step explanation:
First, we have to derive an expression for translation under the assumption that each point of XYZ experiments the same translation. Vectorially speaking, translation from X to X' is defined by:
(1)
Where is the vector translation.
If we know that and
, then the vector translation is:
Then, we determine the coordinates for Y' and Z':
The coordinates are and
