Final answer:
Kamira's pay is modeled by the equation p = 5o + 25, where the base salary is represented by the y-intercept of $25, and the slope of 5 indicates the additional $5 earned per pair of shoes sold.
Step-by-step explanation:
The linear equation that models the relationship between Kamira's pay (p) and the pairs of shoes (o) she sells is p = 5o + 25. In this equation, the base salary of $25 represents the y-intercept, which is what Kamira earns before selling any shoes (when o = 0). The slope of the equation is 5, which represents the additional $5 she earns for every pair of shoes sold.
The independent variable in this situation is the number of pairs of shoes sold (o), and the dependent variable is Kamira's pay (p). The relationship signifies that as Kamira sells more shoes, her pay increases linearly according to the slope.
