Question 1102782
<font face="Times New Roman" size="+2">


Calculate the slope and the y-intercept of the line represented by your given equation.  Then calculate the slopes and y-intercepts of the lines represented y the possible answers you are given.  If the slopes are equal and the y-intercepts are different, then the lines are parallel.  If the slopes are equal and the y-intercepts are the same, then the equations represent the same line.  If the slopes are negative reciprocals of each other, for example, if one line has a slope of 3 and the other has a slope of *[tex \Large -\frac{1}{3}], then the lines are perpendicular.
