Identify Line Type: Identify the type of line and shading on the graph. The line is solid and shaded below, indicating "less than or equal to."
Find Slope and Y-Intercept: Determine the slope and y-intercept of the line from the graph. The line crosses the y-axis at −1 and rises 2 units for every 1 unit it moves right, so the slope (m) is 2.
Write Equation in Slope-Intercept Form: Write the equation of the line using the slope-intercept formy=mx+b, where m is the slope and b is the y-intercept. Here, m=2 and b=−1, so the equation is y=2x−1.
Convert Equation to Inequality: Convert the equation of the line to an inequality. Since the shading is below the line, the inequality is y≤2x−1.
