What is the equation of the line that passes through the point (1,3) and has a slope of -3?

Answer 1

find the line with slope -3, going through

the point (1,3)

use a general form for the linear equation in point slope form y-k = m(x-h) where m= slope and (h,k) is a point on the line = (1,3). h=1, k =3. (y-k)/(x-h) = m

y-3 = -3(x-1)

y-3 =-3x +3

y=-3x +6
