linear equations and inequalities to solve problems involving distance rate time and other practical applications Mastering the Fundamentals 1 Linear Equations and Their Forms SlopeIntercept Form y mx b This form highlights the slope m and yintercept b of the line making it ideal for quickly identifying key features and graphing the equation Standard Form Ax By C This form emphasizes the relationship between the coefficients of x and y offering a structured way to represent linear equations and solve systems of equations PointSlope Form y y1 mx x1 This form utilizes the slope m and a given point x1 y1 on the line providing a flexible way to write equations based on specific data points 2 Graphing Linear Equations Understanding Slope The slope represents the rate of change of the line describing how much the yvalue changes for every unit increase in the xvalue Intercepts The xintercept is the point where the line crosses the xaxis y 0 and the y intercept is the point where the line crosses the yaxis x 0 3 Solving Linear Equations Combining Like Terms Combine terms with the same variable and exponent to simplify equations Distributive Property Apply the distributive property to multiply a constant by a sum or difference within parentheses Isolating the Variable Use inverse operations to move all terms containing the variable to one side of the equation and constant terms to the other ultimately solving for the variable 4 Linear Inequalities Solution Sets The solution set of an inequality consists of all values of the variable that satisfy the inequality Graphing Inequalities Inequalities are graphed on a number line using an open circle to represent a strict inequality less than or greater than and a closed circle to represent an inclusive inequality less than or equal to or greater than or equal to 5 Systems of Linear Equations 3 Substitution Method Solve one equation for one variable and substitute the expression into the other equation leading to an equation with one variable that can be solved Elimination Method Multiply equations by appropriate constants to create opposite coefficients for one variable allowing you to eliminate that variable by adding the equations together Graphing Method Graph both equations on the same coordinate plane the point of intersection represents the solution to the system Practice Problems Solve for x 2x 5 11 Find the slope of the line y 3x 2 Graph the equation y 2x 1 Solve the system of equations x y 5 2x y 4 Write an inequality that represents the following statement The temperature is at least 70
