Suppose you are driving from work to home on a highway. Variables speed (X) and time (Y) for your trip to get home are inversely proportional. So, we can write: Y= K/X, where K is called constant of proportionality. It took you 2 hours to get home from work, and your speed was 55 miles/hour, what is the value of constant K? 22.5 110 None of these answers
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
