To get a feel for the graph of \( y = -\frac{2}{5}x + 3 \), let's consider its key features! This equation is in slope-intercept form (y = mx + b), where the slope (m) is -2/5, indicating that for every 5 units you move to the right on the x-axis, you move down 2 units on the y-axis. The y-intercept (b) is 3, meaning the line crosses the y-axis at the point (0, 3). Plot these points, and you can see this line gently slopes downwards from left to right! When drawing the line, a common mistake is to misinterpret the slope's direction. Remember, a negative slope means the line tilts downward! Also, ensure to label the axes clearly to avoid confusion; this will help you visually track the changes in y as x increases. Always double-check your points to confirm the line’s accuracy!
