Find the equation of the line passing through the points (-2/3,1) and (-2,1/2). Write the equation in standard form.
7nadin3 [17]
Standard form is y = mx + b.
To find the slope, m, we must find the 'rise over run,' or the difference in y divided by the difference in x. We do this by:
\frac{y1 - y2}{x1 - x2}  =  \frac{ (-  \frac{2}{3} ) - ( -2 )}{(1) - ( \frac{1}{2} ) } =  \frac{ \frac{4}{3} }{ \frac{1}{2} } \\  =  \frac{4}{3}  \times  \frac{2}{1}  =  \frac{8}{3}
Therefore, the slope is 8/3.

To find b, we must plug in the slope and one point:
(1) = ( \frac{8}{3} )( -  \frac{2}{3} ) + b \\ 1 =  -  \frac{16}{9}  + b \\  \frac{25}{9}  = b
Therefore, b is 25/9, and the total equation is
y =  \frac{8}{3} x +  \frac{25}{9}
