A health science-kinesiology program to lose weight collected data from ten students. Sex was coded as 1=female and 0=male. The regression equation obtained by using a statistical software was: Pounds lost 15.8 + 0.65 time + 6.00 sex For the same length of time in the program, the weight loss of a female compared to a male is: 19.05 more pounds. 15.8 less pounds. 3.25 more pounds. 25.05 less pounds. O 6 more pounds.

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.
