Plot Y-Intercept: Plot the y-intercept on the graph.The y-intercept is the point where the line crosses the y-axis. For the equation y=3x−1, the y-intercept is at (0,−1). Place a point on the graph at (0,−1).
Find Another Point: Use the slope to find another point.The slope of 3 means that for every 1 unit increase in x, y increases by 3 units. Starting from the y-intercept (0,−1), move 1 unit to the right (increasing x by 1) and 3 units up (increasing y by 3). This gives us another point on the line, which is 12. Plot this point on the graph.
Draw Line: Draw the line through the points.Using a straight edge, draw a line through the points (0,−1) and (1,2). This line represents the graph of the equation y=3x−1.
Identify Correct Graph: Identify the correct graph among the options.The correct graph will be a straight line that passes through the points (0,−1) and (1,2). Without the actual graphs labeled (A), (B), (C), and (D), we cannot visually confirm which graph corresponds to the equation. However, the description provided should match one of the options given.
