Question

Find the slope of the line through (-9, -10) and (-2, -5).
A) - 5/7
B) 7/5
C)5/7
D)- 7/5

Answer 1

Please help!!

Answer 2

sloe formula:
(y1-y2)/(x1-x2)

Answer 3

*slope

Answer 4

(-10+5)/(-9+2)=?

Answer 5

solve

Answer 6

\[\frac{ y_1-y_2 }{ x_1-x_2 }=\frac{ -10-(-5) }{ -9-(-2) }=\frac{ -10+5 }{ -9+2 }=?\]

Answer 7

If I call with \((x_1,y_1)=(-9,-10)\), and with \((x_2,y_2)=(-2,-5)\), then the slope \(m\) of such line is given by the subsequent formula:
\[\Large m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}} = \frac{{ - 5 - \left( { - 10} \right)}}{{ - 2 - \left( { - 9} \right)}} = ...?\]

Answer 8

-5/7?

Answer 9

no

Answer 10

-10+5=-5
-9+2=-7

Answer 11

thus (-5)/(-7)=?

Answer 12

hint:
\(-5-(-10)=-5+10=...?\)

Answer 13

similarly:
\(-2-(-9)=-2+9=...?\)

Answer 14

5/7?

Answer 15

that's right!
