The equation that represents a proportional relationship is m = -0.5b
Proportional relationship
Two variables are said to be proportional if an increase in one variable leads to an increase in other variable and a decrease in one variable leads to an decrease in other variable.
Given that m ∝ b
m = kb
When m = 3, b = -6, hence:
3 = -6k
k = -0.5
m = -0.5b
