Basically you find the data points and fill in the values. For Point J it is (2,4). They want you to do this: (2-4,4-6)...it then becomes (-2,-2).
So
J: (-2,-2)
K: (-1, -4)
I: (-2, -5)
Those are your new points. I hope this helps love! :)
Some basic dimensions could be 4x1 and 3x2
The y intercept is (0, 1)
Y=3x2+1
Hope this helped :)
