ok ?

33. What is the slope of the line that passes through the pair of points? (–2, 7), (18, 1) (1 point)

5. ikshjbdckoj

|dw:1360199929695:dw|

6. Luis_Rivera

(-2,7)-(18,1) m=(1-(7))/(18-(-2)) m=(1-(7))/(18+2) m=(1-(7))/(20) m=(-6)/(20) m= -3 / 10

7. mathsmind

-3/10

8. mathsmind

$m= \frac{ y_2-y_2 }{ x_2-x_1 }$

9. Luis_Rivera

jeez, looks just like mine

10. ikshjbdckoj

Thank ya'll!! Can you help me wit another one?

11. mathsmind
