Line passes through (2, -1) and slope of 1/3

Step 1

y = mx + b, Identify: x = 2, y = -1, slope:
\sf (1)/(3)

insert following values


\rightarrow \sf -1 = (1)/(3) (2) + b

multiply


\rightarrow \sf -1 = (2)/(3) + b

switch sides


\rightarrow \sf b = -1 - (2)/(3)

subtract


\sf \rightarrow b = -(5)/(3)

convert to mixed fraction


\sf \rightarrow b = -1(2)/(3)

Step 2

y = mx + b, m =
\sf (1)/(3), b =
-1(2)/(3)

insert following values


\rightarrow \sf y = (1)/(3) x -1(2)/(3)
