Answer

$y=3x-1$

Work Step by Step

The given line has a slope of 3 and goes through the point (1,2). We can write this line in point-slope form $y-y_{1}=m(x-x_{1})$ with $m=3$ and $(x_{1},y_{1})=(1,2)$. $y-2=3(x-1)=3x-3$ Add 2 to both sides. $y=3x-1$ This line is now in the slope-intercept form of $y=mx+b$.
