If you want to find the equation of line with a given a slope of which goes through the point (-3,6), 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

Add 6 to both sides to isolate y

Combine like terms and to get

Remove the zero term

Answer:


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


which is now in form where the slope is and the y-intercept is

Notice if we graph the equation and plot the point (,), we get (note: if you need help with graphing, check out this solver)

Graph of through the point (-3,6)
and we can see that the point lies on the line. Since we know the equation has a slope of and goes through the point (-3,6), this verifies our answer.
