600 x 40 I think the new dimetions will be
Let point A be
and point B 

Use the point-slope formula and whichever point you want as , in this case I'll use

So you're combining equations correct?
Answer:
B. f(x) is shifted left by 6 units
Step-by-step explanation:
when we talk about translations, we know they happen along the X axis, y axis or sometimes both, in this case we see that were subtracting x by six units, so we are moving left along the x axis
ways to remember this is:
-you count up x the RIGHT way going right
-you count UP y
and of cource by process of ellimination we know that decreasing X goes left and decreasing y goes down
ALSO NOTE: x always goes horizontally and y always goes vertically
X is 25 beceause 25-10=15
