We can find slope 
with this formula
Where 
and 
thus
The slope of line is -1/2.
Hope this helps.
So, you start out with 100 students. 85% are good students, so 85 good students. If 10 more good students were to join the school, then your total of 100 would increase by 10. 100+10=110. Your number of good students would also increase by 10. 85+10=95. To find the new percent, do division. 95/110 rounds to 86%.
Given:
Different types of congruence postulates.
To find:
Which cannot be used to prove that two triangles are congruent?
Solution:
According to AAS congruence postulate, if two angles and a non including sides of two triangles are congruent, then triangles are congruent.
According to SAS congruence postulate, if two sides and an including angle of two triangles are congruent, then triangles are congruent.
According to SSS congruence postulate, if all three sides of two triangles are congruent, then triangles are congruent.
AAA states that all three angles of two triangles are equal and no information about sides.
So, it is a similarity postulate not congruent postulate. According to AAA two triangles are similar not congruent.
Therefore, the correct option is D.
