I keep getting this one wrong for some reason

@Will.H @retirEEd @jhonyy9 @YumYum247

OpenStudy (will.h):

4 units to the right and 5 units down translation so this would be the rule (x + 4 , y - 5) So all you have to do is get the coordinates of the triangle and apply that rule above on them

OpenStudy (will.h):

For example the point (-1,3) --> (x+4,y-5) --> (-1+4 , 3-5) --> (3,-2) that's how it is done Now do the same to the other 2 points

check my answer @Will.H

OpenStudy (mrnood):

nit sure what problem you are having. Just count from each point 4 to the right (that means x -> x+4) 5 down (that means y -> y-5) so the top point of the triangle is (-1,3) which means x=-1 y=3 so add 4 to x: -1+4 = 3 and subtract 5 from y: 3-5 = -2 so the transformation is (-1,3) -> (3,-2) do exactly the same for the other 2 points

OpenStudy (devonhoward15):

i did that and it kept saying wrong

OpenStudy (will.h):

The other point (2,-1) --> (x+4 , y-5) --> (6,-6) The other point (-5,-3) --> (-1,-8) you have error in those 2 points

OpenStudy (mrnood):

yes - as @Will.H says - you have made a mistake in the othe 2 points remember to start from the original position of the point and go x+4, y-5

OpenStudy (will.h):

Cheers MrNood C ya 2

OpenStudy (mrnood):

You should be able to check your work - because this is a simple 'translation' then the 2 triangles should look exactly the same size and shape. You can see that your 2 triangles are not the same
