y – y1 = m(x – x1) this is the formula, if that's all you need

Hi, Heres a example: You are given the point (4,3) and a slope of 2. Find the equation for this line in point slope form. Solution: Just plug the given values into your point-slope formula above. Your point (4,3) is in the form of (x1,y1). That means where you see y1, use 3. Where you see x1, use 4. Your slope was given to you, so where you see m, use 2. Pretty simple, huh? Your final result should look like: y-3=2(x-4) More Practice: Your point is (-1,5). The slope is 1/2. Create the equation that describes this line in point-slope form. Try working it out on your own. The answer is: y-5=.5(x+1) . If that's not what you got, re-read the lesson and try again.

Well, just replace y1 with 1 x1 with 2 and m with 3

so if its asking for an equation you dont have to solve it?

I dont think so, unless it says solve for ____

It says "Write an equation of the line in point-slope form through the given point and with the given slope m."

so do they just want the formula with the numbers plugged in or do they want it solved also?

Well, it doesn't say to solve it, does it?
MaeganR
  • MaeganR
Nope

  • anonymous
so I think that's it!
