Answer:
A: (-1,0)
B: (1,1)
C: (5,3)
(0,½)
(7,5) doesn't lie on the line
Step-by-step explanation:
Slope: (3-1)/(5-1) = ½
y = ½x + c
0 = ½(-1) + c
c = ½
y = ½x + ½
(0,½) is on the line
y = ½x + ½
Check for (7,5)
5 = 7/2 + 1/2
5 = 4 is a false statement
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
Answer:
8x+2y+3x-18y+x^2
final answer: x^2+11x-16y

Answer:
As problem is of regression analysis,thus r^2 will be 24 and sy/x is 4.
