A line passes through the point (-2, 3) and has a slope of -2. What is the equation of the line?
Mrrafil [7]

Answer:

y = -2x -1

Step-by-step explanation:

slope intercept form is y = mx +b

m = slope, b = y intercept

point is given as ordered pair (x,y)

plug in slope into y=......

y= -2x+b

plug in the point

3 = -2 * (-2) + b

3= 4 +b subtract 4 on each side

b = -1

y = -2x -1

A function is created to represent the costs of living per person in the family. What restrictions would be made to the domain?
Nitella [24]

Let

x-------> the number of persons in the family

f(x)------> the function represent the cost of living

we know that

The domain of the function  would only include positive integers, because the number of persons can not be negative or a fraction

The range of the function would only include positive numbers, because the cost can not be negative

therefore

<u>the answer is the option B</u>

The domain would only include positive integers.
