ANSWER
it is the one that is highlighted Yellow
f=±✓de/4e
photo is how you do the work
for A you should take each plotted point and change the sign of the x values. for example (-1,3) should become (1,3) and (-4,4) should become (4,4)
for B take each point and flip the variables and x's sign. (-1,3) should become (3,1)
for C take every x value and subtract 2. (-1,3) should become (-3,3)
for D take each point and flip the variables and y's sign. (-1,3) should become (-3,-1)
This is a proportion problem. Let the monument me x feet tall.
40/x=5/6
Cross multiply:
240=5x
x=48 ft.
So the monument is 48 ft tall,
