Four students were discussing how to find the unit rate for a proportional relationship. Which method is valid?
A. "Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the u
B. "Look at the graph of the relationship. Count the number of units up and the number of units to the right one must one move to arrive at the next point on the graph. Write these two numbers as a fraction."
C. "Look at the graph of the relationship. Find the x-value of the point that corresponds to y = 2. That value is the unit rate.”
D. "Look at the graph of the relationship. Find two points which have y-values that are one unit apart. The unit rate i
difference in the corresponding x-values."

Im not sure..! Hopefully you find he answer soon!

Step-by-step explanation:

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students.   an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality.   in the case of brown v. board of education, that standard was challenged and defeated.   segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
