Answer:
-2
Step-by-step explanation:
The slope is always the coefficient of x divided by the coefficient of y (if they are on opposite sides of the "=")
SO...
-2/1 = -2 = Slope
136/160=x/100
Cross multiply and divide:
136*100=13600
13600/160=85
Answer: 85%
direct variation
y = kx
substitute in and solve for k
14 = k(-4)
14/-4 =k
k = -7/2
y = -7/2 x
y = -7/2 * -6
y = 42/2 = 21
