Identify the equation of the line given: \(y = -\frac{4}{5}x + 2\). This is in slope-intercept form \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept.
Locate the y-intercept \(b = 2\) on the graph. This is the point where the line crosses the y-axis, so plot the point \((0, 2)\).
Use the slope \(m = -\frac{4}{5}\) to find another point. The slope means that for every 5 units you move to the right (positive direction on the x-axis), you move 4 units down (negative direction on the y-axis). Starting from \((0, 2)\), move right 5 units to \(x=5\) and down 4 units to \(y = 2 - 4 = -2\), so plot the point \((5, -2)\).
Draw a straight line through the points \((0, 2)\) and \((5, -2)\) extending in both directions. This line represents the graph of the equation.
Verify the line by checking if other points satisfy the equation or lie on the line, ensuring the slope and intercept are correctly represented.
