![]() Use variables to represent two quantities in a real-world problem that change in relationship to one another write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Grade 6 – Expressions and Equations (6.EE.C.9).Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes. The perimeter of rectangle ABCD is 5 + 5 + 6 + 6 = 22 units OR 2 \, (6) + 2 \, (5) = 22 units To find the perimeter of a rectangle, add up each of the side lengths or use the formula, P=2l + 2w Now that you know the side lengths, you can find the perimeter of the rectangle ABCD. The distance between points is always positive because distance is a positive measurement. The distance from point C to point B is 6 units. The distance from point D to point C is 5 units. The distance from point A to point D is 6 units. The distance from point A to point B is 5 units. To do this, count the number of units from one point to the next. Let’s find the side lengths of the plotted rectangle. Let’s plot the polygon on the coordinate plane with vertices at A \, (4, 2), B \, (4,-3), C \, (-2, -3), and D \, (-2, 2). The distance from point A to point B is 7 units. To find the distance from point A to point B, count the number of units. Plot the point A \, (-4, 4) and the point B \, (3, 4). We can find the distance between two points on a graph by counting the number of units between the points. ![]()
