Eighty-one thousand two hundred seventy-one.
Answer:
m = -3
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
We use two points
(0,-4) and (-2,2)
m = (2 - -4)/(-2 -0)
= (2+4)/(-2-0)
=6/-2
= -3

Answer:
$4
Step-by-step explanation:
The equation for direct proportionality =
y = bx
where y = dependent variable
b = constant
x = independent variable
There is positive proportionality is two variables are positively related to each other.
In this question, price of lunches is the dependent variable while number of lunches is the independent variable
$16 = b4
Divide both sides by 4 to find b
b = $4
