Using Slope and y intercept (Skill #4)
Use the formula
![\[m=\frac{y_2-y_1}{x_2-x_1}\]](http://www.tentotwelvemath.com/wp-content/ql-cache/quicklatex.com-af82d1004a3cfbede13462c3e81bbeb5_l3.png "Rendered by QuickLaTeX.com")
to find the slope of each line. Use the vertical intercept to complete the equation in the form
![\[y=mx+b\]](http://www.tentotwelvemath.com/wp-content/ql-cache/quicklatex.com-dbd358db094bbb48233e71e18917ad7e_l3.png "Rendered by QuickLaTeX.com")
