Austin believes that his score on an upcoming test can be modeled by the equation y=7.2x+53 where x represents the number of hours spent studying, and y represents Austin's test score. Assuming this equation is accurate, predict Austin's test score if he studies for 2 hours. Assuming this equation is accurate, predict Austin's test score if he studies for 3.5 hours
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.
