Answer:
77
Step-by-step explanation:
Firstly, we need to calculate the total score of the junior students and the total score of the senior students.
The total score of the junior students is 35 * 80 = 2,800
The total score of the senior students is 15 * 70 = 1050
The total score is thus 2,800 + 1,050 = 3,850
The average score of the 50 students is thus 3,850/50 which equals 77

Answer:
y-9=2(x-3)
Step-by-step explanation:
The point-slope formula is: y-y1=m(x-x1)
y1 and x1 is where you plug in the coordinate and m is the slope.
y1 is the second number of the coordinate (x, y)
So, y1 is 9 in this case
x1 is the first number of the coordinate (x, y)
So x1 is 3 in this case
