Parallel lines share the same slope. y=3x+7 has a slope of 3, so that is the slope of the parallel line. Then use y=mx+b an plug in (2,4).
y=3x+b
4=3(2)+b
4=6+b
b=-2
So the equation is y=3x-2
the question says that the samples included 100 people each, so it's just 100 multiplied by the amount of samples:
7×100=700
Answer:
1/5
Step-by-step explanation:
= 25 so x = -2 because 
= 25
if x = -2 then plug in: 5^1/2(-2) = 5^-1 = 1/5

Answer:
-3
Step-by-step explanation:
f(x) = x2 – 4
replace x with -1
f(-1) = (-1)^2 – 4
= -3
