Please answer it would mean so much to me :)
maxonik [38]

Answer:

y = \frac{1}{3} x + 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y = 4 ( subtract 3x from both sides )

y = - 3x + 4 ← in slope- intercept form

with slope m = - 3

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-3} = \frac{1}{3}

Given c = 2 , then

y = \frac{1}{3} x  + 2 ← equation of perpendicular line

What is the domain for the piece of the function represented by f(x)=x+1
babunello [35]

Answer:

(-∞, ∞)

Step-by-step explanation:

As you can see for each value of x , f(x) is defined

example , for x = -8000 , f(x) is defined to be -7999.

                 for x = 0 , f(x) is defined to be 1.

                 for x = 8000 , f(x) is defined to be 8001.

Also,

By its graph , Which is a straight line , So, it is defined everywhere

Thus,

its domain is (-∞, ∞)
