Question

Find the slope of a line parallel to each given line.
y = 1/3x +1

Answer 1

bearing in mind that parallel lines have exactly the same slope, hmmm what's the slope of the one above anyway?

`\bf y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{3}}x+1\qquad \impliedby \begin{array}ll \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}`
