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

---Point-Slope Formula---
where m 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)

Distribute

Multiply the negatives

Multiply and to get

Add to both sides

Combine like terms

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 (so this shows our equation has a slope of ) and the y-intercept is

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

Graph of through the point (,)
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 (,), this verifies our answer.
