Answer:
B.
Step-by-step explanation:
there is not much to explain.
a strong correlation means there is a direct connection.
so, a change in a causes immediately a change in b.
and positive means that the changes go in the same sign direction. increase => increase. decrease => decrease.
To get the slope, you need the form y=mx+b where m is the slope of the line, so add 6x to both side you get
-2y=6x-10
Then divide by -2
y=-3x+5
The slope form is y=-3x+5 with the slope being -3
Answer:
16
Step-by-step explanation:
1) Plug x=1 into equation
f(x) = -2(1)²+4(1)+6
f(x) = -2²+4+6
f(x) = 4+4+6
y = 14
(1,14)
2) Plug in x=2 into equation
f(x) = -2(2)²+4(2)+6
f(x) = -4²+8+6
f(x) = 16+8+6
y = 30
(2,30)
3) Use slope formula (
)
16
For A I am pretty sure it's 12.6 and for B I believe it's 15.7
