Question 328877
<font face="Garamond" size="+2">

Take all of the answer equations and put them into slope-intercept form, to wit: *[tex \Large y\ =\ mx\ +\ b]

Once you have done that, select the answer that has the same slope number as the given equation because:

*[tex \LARGE \ \ \ \ \ \ \ \ \ \  L_1\ \parallel\ L_2 \ \ \Leftrightarrow\ \ m_1\ =\ m_2]

The slope number is just the coefficient on *[tex \Large x] once the equation is in slope-intercept form.
