Vocab
Proportional Relationship - when two ratios are equal, they are said to have a proportional relationship.Algorithmic approach - using a list of well-defined instructions or a step-bystep procedure to solve a problem. Fluently – efficient and accurateUnit Rate - when rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour.Scale drawings - a drawing that shows a real object with accurate sizes except they have all been reduced or enlarged by a certain amount (called the scale).Origin - the point on a coordinate plane in which the x and y axes intersect; the ordered pair for the origin is (0, 0). |
