            <p>Linear equations in two variables might sound big, but they’re simply equations like ax + by = c that describe straight lines. In this course, you’ll learn what variables, coefficients, and constants mean, and how a pair (x, y) can make an equation true. You’ll get friendly practice with the coordinate plane—axes, origin, quadrants—and become confident plotting points and connecting them to make a line. We’ll compare these to one-variable equations, explore real-life examples like money and distance-time, and understand why a line has infinitely many solutions.</p>

<p>As you build your skills, you’ll meet the most useful forms of linear equations: standard form (ax + by = c), slope-intercept form (y = mx + b), and intercept form (x/a + y/b = 1). You’ll discover slope as “rise over run,” read the y-intercept from an equation or graph, and graph lines using tables and intercepts. Then you’ll apply these ideas to check whether a point lies on a line, spot parallel and perpendicular lines, and turn short stories into equations. Finally, you’ll solve systems of two equations by graphing and by a starter version of substitution, interpret intersections, and practice with quick wins, real-world graphs, and plenty of short quizzes to lock in your understanding. By the end, you’ll know how to choose the right form, graph accurately, explain what slope and intercept mean in context, and avoid common mistakes—ready for bigger algebra adventures.</p>
