Brittany and her friends are going on a 550 mile road trip. They intend to drive all the way without stopping. After driving a total of 8 hours, they are 150 miles away from their destination. After driving a total of 11 hours, they are 0 miles away from their destination. If D represents the remaining distance to their destination and t represents the amount of time (in hours) that they have beeng driving, find the linear equation relating D and t. D=
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.
