## Intermediate Algebra (6th Edition)

Using $y=mx+b$, the given equation, $y=-5x ,$ has the following characteristics: \begin{array}{l}\require{cancel} \text{Slope: } m=-5 \\\text{$y$-intercept: } b=0 .\end{array} To graph this line, start with the $y-$intercept of $( 0,0 )$. From the $y-$intercept, the slope, $m= -5=\dfrac{-5}{1}$ can be interpreted as moving $5$ units down and $1$ unit to the right. Hence, the second point for graphing is the point $( 1,-5 )$.
