Question:
The diagram below shows the graph of a proportional relationship. The plotted point is (6,9) .
What is the unit rate of this graph? Be sure to simplify your answer.
Answer:
The unit rate of this graph is 1.5
Explanation:
The graph shows a proportional relationship and the plotted point is (6,9).
The unit rate of the graph can be determined by the formula,

Thus, from the graph, the coordinates are (0,0) and (6,9)
Substituting the coordinates in the formula, we have,

Subtracting, we get,

Thus, the unit rate of the graph is 1.5
Heberto could go 14 blocks East and 14 blocks south, so the last answer
The least-square regression line has a slope of:
m=(nΣxy-ΣyΣx)/(nΣx²-ΣxΣx)
and a y-intercept of:
b=(Σy-mΣx)/n
In this case: n=7, Σxy=4899, Σy=391, Σx=85, Σx²=1153 so
m=(7(4899)-391*85)/(7(1153)-85*85))=1058/846
b=(391*846-85*1058)/(7*846)=34408/846
So the line of best fit is:
y=(1058x+34408)/846 and if we approximated this as your answers see to have done....
y=1.25x+40.67
Answer:
The average number of students in each grade is 131 students
Step-by-step explanation:
In order to get this answer, you will divide 786 by 6 because 768 is the number of students in your school and 6 is the number of grades. Once you divided 786 and 6, you should get 131. Hope this helps! :)
