WebTo solve a system of equations by elimination, write the system of equations in standard form: ax + by = c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite. Then, add or subtract the two equations to eliminate one of the variables. WebFree Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step

WebUse a graphing calculator to verify your work. y − 3 x = − 2 The slope is m = (Simplify your answer.) The y-intercept is (Type an ordered pair. Simplify your answer.) Use the graphing tool to graph the equation. Use the slope and y-intercept when drawing the line. WebWe now locate the ordered pairs (-3,9), (-2,7), (-1,5), (0,3), (1,1), (2,-1), (3,-3) on the coordinate plane and connect them with a line. We now have the graph of 2x + y = 3. The line indicates that all points on the line satisfy the equation, as well as the points from the table. The arrows indicate the line continues indefinitely. pool sprayer
