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

i think, i am right it should be A

Answer 1

To find the slope of the line, use the slope formula:
`( y_(2) - y_(1) )/( x_(2) - x_(1) )`

`(-5 - (-10))/(-2 - (-9)) = (5)/(7)`
The slope should be 5/7 so your answer should be C.

Answer 2

Slope = Y2-Y1/X2-X1
Slope = -5+10/-2+9
Slope = 5/7
So it's C actually
