Question

Can you help me with 17,18,19,20,21

Answer 1

Answer:

See Below

Step-by-step explanation:

#17. You just have to plot the points, this should be super easy. Go to the left 6 (because it is negative) then up four. This is M. Then go right 5 and up 4 and plot A.

#18. Point T is a reflection of A over the X-axis. This is quite simple as well. All you need to do it make your Y coordinate negative? Why Y? You'll see. You need to essentially "fold" the graph at the X line, so your Y value goes from up top at 4 to below the X axis as we're reflecting over the X line. I hope that makes sense. T should be at 5,-4

#19 This is the same process as 18, Over the X coordinate. Make Y negative and plot it. It should be H= -6,-4

#20 You can get this from the answers from #18 and #19.

#21. The formula is Base*2+Height*2, or Base+Base+Height+Height. You want the distance around. I'll have you figure this out, but if you get comment and I'll check back. How many steps do you go up from T to A? How about over from H to T 9 or (M to A)? Once you find how many units your base and height are, use the formula for perimeter to find the answer. Hope this helps! :)
