Slope = change in Y over change in X:
Slope = (1 - 8) / (5-9)
Slope = -7/-4
Slope = 7/4
Answer:
it is not a direct variation
Step-by-step explanation:
To have a direct variation
y/x = k for all values of x and y
y/x = 11/7
y/x = 13/8
y/x = 15/9 = 5/3
y/x = 17/10
11/7 does not equal 13/8 so it is not a direct variation
