A. y =1/3 x + 4
B. y =1/3 x - 4
C. y = -1/3x - 4
D. x = 1/3y - 4

the answer is  b. hope that helped

The equation of line in  slope intercept form  is [tex]y = \frac{1}{3} x-4[/tex].

What is equation of line in slope intercept ?

A linear equation in the form of y = mx + b is called a slope intercept form of line. In which m is the slope and  b is the y intercept.

Let the equation of line in slope intercept form be [tex]y = mx + b[/tex] .

According to the given question

We have

A slope of line, m = 1/3.

And, a point (0,-4).

Substitute, m = 1/3, x = 0 and y = -4 in the equation y = mx +b.

⇒ [tex]-4 =\frac{1}{3}(0) + b[/tex]

⇒ [tex]b = -4[/tex]

Therefore, the slope intercept form of the line is [tex]y = \frac{1}{3} x-4[/tex].

( By substituting m = 1/3 and b = -4 in y = mx + b)
