Find the slope of the line that passes through each pair of points. (-3,-3),(-7,-5)

Question

anonymous · Answer

m = rise/run

-5 - (-3) = -2
-7 - (-3) = -4

-2/-4 = 1/2

m = 1/2

Can you please explain I do not understand.

slope = $$\frac{y_2 - y_1}{x_2 - x_1}$$ y2 means y coordinate of the second ordered pair

y1 is the first y

x1 is the first x

x2 is the second x therefore $$slope = \frac{-5 - (-3)}{-7 - (-3)}$$ $$slope = \frac{-5 + 3}{-7 + 3}$$ $$slope = \frac{-2}{-4}$$ $$slope = \frac{1}{2}$$

Hi Sorry.  Ok so to make sure I understand.  Because I wrote the points wrong.  (-9,-3),(-7,-5)  m= -2/2  wich then turns to -1 ?  Yes?

lgbasallote · Answer

yes
