Find the equation (in y = mx + b form) of each line described below. Homework Help ✎

1. A line with slope $\frac { 1 } { 2 }$ passing through the point (6, 1).

2. The line y = 2x + b passing through the point (1, 4).

$y=\frac{1}{2}x-2$

y = 4 when x = 1. Substitute these values into the equation and then solve for b.
