Question 184093
</pre><font size=4><b>
Given: {{{Slope=m[1]=2/5}}}
a) what is the slope of the line paralle to it?
Answer: remember for parallel lines; {{{m[1]=m[2]=highlight(2/5)}}}, the same slope 
(b) what is the slope of the line perpendicular to it
Answer: Remember for perpendicular lines: {{{m[2]=-1/m[1]}}}, it's the negative reciprocal: {{{m[2]=-1/(2/5)=highlight(-5/2)}}}
Thank you,
