find the slope of the line through (-9 -10) and (-2 -5)

A.-5/7
B.7/5
C.5/7
D.-7/5

i think, i am right it should be A

Respuesta :

Slope = Y2-Y1/X2-X1
Slope = -5+10/-2+9
Slope = 5/7
So it's C actually
To find the slope of the line, use the slope formula: [tex] \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } [/tex]
[tex] \frac{-5 - (-10)}{-2 - (-9)} = \frac{5}{7} [/tex]
The slope should be 5/7 so your answer should be C.
