Write an equation of a line in point slope form that has a slope of -3 and passes through the point (3, -4). Do not use spaces and enter fractions as improper reduced fractions when needed.
hmmm,check this http://openstudy.com/study#/updates/4ff5ff4de4b01c7be8c90c78
use the formula \[\huge y - y_1 = m(x-x_1)\]
ok ok ok ok ok i need step-by-step here... except doin what Igba put.. that would be step one lol
where m=slope (3,-4)=(x1,y1)
it's really straightforward..just substitute :)
Just substitute of the variables in Lgba's formula ..
