Answer:
Protractor
Step-by-step explanation:
A POSTULATE, LAW OR THEORY SHOULD NEVER BE ALTERED
∴ The protractor postulate states that the measurement of an angle between two rays can be designated as a unique number, and this number would be between 0 and 180 degrees, Hence for every angle A, there corresponds a positive real number less than or equal to 180. This postulate guarantee the use of a protractor to measure angles.
Hence, Given line AB and point O on that line in such a way that any ray that can be drawn with its endpoint at O can be put into a one- to-one correspondence with the real numbers between 0 and 180 is a statement that explains Protractor's Postulate.

Answer:
y = -1/2x +7/2
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (5-3)/(-3-1)
= 2 /-4
= -1/2
We can use the slope intercept form
y= mx+b where m is the slope and b is the y intercept
y = -1/2 x+b
Substitute the point int
3 = -1/2 (1) +b
3 = -1/2 +b
Add 1/2 to each side
62 + 1/2 = b
b = 7/2
y = -1/2x +7/2
