Respuesta :
Answer:
-1/6
Step-by-step explanation:
(10 - 8)/(-21 + 9)= 12/-12= -1
y - 8 = -1(x + 9)
y - 8 = -x - 9
y = -x - 1
Answer:
slope = -1/6
Step-by-step explanation:
To find the slope:
1) find the change in the y values and the change in the x values.
change in y = 8 - 10 = -2
change in x = -9 + 21 = 12
2) divide the change in y and the change in x
slope = -2/12 = -1/6
