Question

Find the slope of the line that contains the following points.

R(-3, 5), S(3, -2)

Answer 1

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.

Answer 2

i thought it was y2-y1 ?

Answer 3

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

Answer 4

oh okay

Answer 5

so, what did u get the slope here ?

Answer 6

-7/6

Answer 7

correct! good :)

Answer 8

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)

Answer 9

apply same formula, what slope you get ?

Answer 10

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

Answer 11

6/-8

Answer 12

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

Answer 13

thanks

Answer 14

welcome ^_^
