CPM Homework Help : AC Problem 8-120

Line $L$ passes through the points $\left(-44,42\right)$ and $\left(-31,94\right)$ , while line $M$ has the rule $y=6+3x$ . Which line is steeper? Justify your answer.

Hint:

Since $m$ in $y=mx+b$ is the slope, we know that the slope of line $M$ is $3$ .
Calculate the slope of line $L$ by either using a slope triangle or by finding the change in $y$ and comparing it to the change in $x$ .

Step:

$\frac{42-94}{-44-(-31)}=\textit{m}$
