Question

Write an equation of each line with the given characteristics.

1. slope = 3;
y-intercept = -1

Answer 1

`y=\stackrel{\stackrel{m}{\downarrow }}{3}x\stackrel{\stackrel{b}{\downarrow }}{-1}\qquad \impliedby \qquad \begin{array} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}`
