If you want to find the equation of line with a given a slope of which goes through the point (3,-8), you can simply use the point-slope formula to find the equation:

---Point-Slope Formula---
where is the slope, and is the given point

So lets use the Point-Slope Formula to find the equation of the line

Plug in , , and (these values are given)

Rewrite as

Distribute

Multiply and to get

Subtract 8 from both sides to isolate y

Combine like terms and to get

Answer:

So the equation of the line with a slope of which goes through the point (3,-8) is

Y=mX+b
-8=1/2*3+b
-8=1.5+b
b=-8-1.5
b=-9.5 y intercept
Thus this line equation is:
y=x/2-9.5
