The word for the punctuation mark, on the other hand, comes from Îºá¿¶Î»Î¿Î½ (or kÅlon), which means âlimbâ or âclauseâ â and it is used because one of the main functions of the colon is to separate two clauses, where the second clause explains or follows from the first.
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.
Graphing a Linear Equation. In order to graph a linear equation you can put in numbers for x and y into the equation and plot the points on a graph. One way to do this is to use the intercept points. The intercept points are when x = 0 or y = 0.Here are some steps to follow: You can check your answers by trying other numbers in the equation.t first it may seem strange that an equation represents a line on a graph. To make a line you need two points. Then you can draw a line through those two points. The x and y variables in the linear equation represent the x and y coordinates on a graph.
