Please help, I will give brainliest, I am struggling badly.
Valentin [98]

Answer:

C

Step-by-step explanation:

A line with a slope of 1/3 using the y=mx+b line slope equation would be:

y=1/3x+b

We can now plug the x and y values into this equation with x being -6 and y being 2.

2=1/3 * -6 +b

2= -2 +b

b=4

Therefore the equation is

y=1/3x+4

C

<em>I hope this helps! :)</em>
