you can solve this by analytic geometry rules easily!!
Answer:
1. Use a compass to make arc marks which intersect above and below then connect.
2. 
Step-by-step explanation:
1. To construct a perpendicular line, use a compass to draw arc marks from one end of the segment through point P. Then repeat this again at the other end. This means at point P there will be two intersecting arc marks. Repeat the process down below with the same radius as used above. Then connect the two intersections.
2. The point slope form of a line is
where
. We write
Since the line is to be perpendicular to the line shown it will have the negative reciprocal to the slope of the function 3x+y =-8. To find m, rearrange the function to be y=-8-3x. The slope is -3 and the negative reciprocal will be 1/3.
Simplify for slope intercept form.

XY is the rightmost side of the rectangle. Since you have the image already graphed, you can just <u>count</u> how many units there are from X to Y.
If you are starting at point X and you walk to point Y, how many "lines" do you cross to get there?
Answer: 4 units
Answer:-5
Step-by-step explanation:
2x+7-x+12=14
x+19=14
x=-5
Answer:

This is because modulus number will be always positive
Hope this is correct and helpful
HAVE A GOOD DAY!
