A student's grade in a course is the average of 4 test grades and a final exam that is worth four times as much as each test. Suppose a student has test grades of 89, 88, 89, and 94. Write an equation to model this situation where xxis the student's grade on the final exam and yyis the student's average for the course.
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.
