A linear equation is an equation that describes a straight line on a graph. You can remember this by the “line” part of the name linear equation.<\/p>\n\n\n\n
Standard Form<\/strong><\/p>\n\n\n\n Linear equations have a standard form that looks like this:<\/p>\n\n\n\n Ax + By = C<\/strong><\/em><\/p>\n\n\n\n Where A and B are coefficients (numbers) while x and y are variables. C is a constant.<\/p>\n\n\n\n You can think of the x and y variables as points on a graph.<\/p>\n\n\n\n Example linear equations:<\/strong><\/p>\n\n\n\n You can plug numbers into A, B, and C of the above standard form to make linear equations:<\/p>\n\n\n\n 2x + 3y = 7 Linear Equations Represent Lines<\/strong><\/p>\n\n\n\n At 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.<\/p>\n\n\n\n The x and y variables in the linear equation represent the x and y coordinates on a graph. If you plug in a number for x, you can calculate the corresponding number for y. Those two numbers show a point on a graph. If you keep plugging in numbers for x and y in a linear equation, you will find that all the points together make a straight line.<\/p>\n\n\n\n Graphing a Linear Equation<\/strong><\/p>\n\n\n\n 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:<\/p>\n\n\n\n You can check your answers by trying other numbers in the equation. Try x = 1. Solve for y. Then make sure that that point is on your line.<\/p>\n","protected":false},"excerpt":{"rendered":" A linear equation is an equation that describes a straight line on a graph.
