Solving proportions requires finding the unknown numeric value of a variable within a set of ratios that are being compared. You can use step-by-step techniques to clarify and solve proportion problems by extracting information from word problems or tables and creating an algebraic equation to solve for “x.” Proportion problems can solve for time, distance, rate, amounts, percents.
A line in geometry is has most of the same characteristics as it does in real life (and in algebra). A geometric line is straight, and it extends indefinitely in opposite directions. If two lines meet at a point, then they are said to intersect. An example of a line is shown below; note that the ends of the line have arrows that indicate the line continues indefinitely.
