Question

Find the slope of the line that contains the following points.

R(-3, 5), S(3, -2)

hartnn · Answer

The slope of the line through points (x1,y1) and (x2,y2) is given by :
$\huge m=\frac{y_1-y_2}{x_1-x_2}$
now,just put the values and find m.

anonymous · Answer

i thought it was y2-y1 ?

hartnn · Answer

if its y2-y1 in numerator, then there will be x2-x1 in denominator..
eventually, you will get the same answer...

anonymous · Answer

oh okay

hartnn · Answer

so, what did u get the slope here ?

anonymous · Answer

-7/6

hartnn · Answer

correct! good :)

anonymous · Answer

thanks what about this one 
Find the slope of a line parallel to the line through the given points.

P(-2, 4), Q(6, -2)

hartnn · Answer

apply same formula, what slope you get ?

hartnn · Answer

that would be slope of your paralel line, because parallel lines have same slope :)

anonymous · Answer

6/-8

hartnn · Answer

yes, correct :)
and that would simplify to -3/4 :)
