Answer:

$\sqrt{a^2+b^2+16}$

Step-by-step explanation:

The distance (d) between two points in 3 dimensions is ...

d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)

Then the distance between (a, -b, -4) and (0, 0, 0) is ...

d = √((a -0)² +(-b -0)² +(-4 -0)²)

= √(a² +b² +16)

Answer:

y=14x+56

Step-by-step explanation:

Question says to find the equation in slope intercept form that means we have to use y=mx+b form.

Where b is the initial value or you can say y-value when x=0

Given that at shift x=0, number of people y=56

so that means b=56

now find the difference between consecuitve value of y

70-56=14

84-70=14

98-84=14

We are getting constant difference of 14 so that mean slope m=14

now plug values of m and b into y=mx+b

Then final answer will be y=14x+56
