Find an equation in point slope form for the line having the slope m= -3 and containing the points (7,2)

Question

Please show me the steps how you got to the answer 

Answer 1

Ashley,

The general point-slope form equation is y - y₁ = m(x - x₁).

So in this particular case, you just need to plug in the slope and the point given to you:

 

y - 2 = -3(x - 7)        You're done!

 

The only challenge to this type of problem is knowing the general form.

I hope this helps.
