Exercise 44 Page 350

Equations written in slope-intercept form follow a specific format. In this form, $m$ represents the slope of the line and $b$ represents the $y\text{-}$intercept. The given equation is already in this form, so we can highlight its slope and $y\text{-}$intercept. The $y\text{-}$intercept is $\text{-}1,$ so the graph passes through the $y\text{-}$axis at $(0,\text{-}1).$

Graphing the Equation

A slope of $2$ means that for every $1$ unit we move in the positive horizontal direction, we move $2$ units in the positive vertical direction. To graph the equation, plot the $y\text{-}$intercept and then use the slope to find another point on the line.
