Answer

The line \(-2x + y = -8\) has a slope of \(2\) and a y-intercept at \((0, -8)\). Plot the points \((0, -8)\) and \((1, -6)\) and draw a line through them.

The Deep Dive

To graph the line represented by the equation \(-2x + y = -8\), first, we can rearrange it into the slope-intercept form \(y = mx + b\). Adding \(2x\) to both sides gives us \(y = 2x - 8\). The slope \(m\) is 2, meaning for every 1 unit you move to the right on the x-axis, you move 2 units up on the y-axis. The y-intercept \(b\) is -8, indicating the line crosses the y-axis at (0, -8). Plot the y-intercept and use the slope to find another point, such as (1, -6). Draw the line through these points! Don’t worry if the equation looks a bit complicated at first; once you get the hang of graphing linear equations, you'll find it pretty straightforward. Just remember, being alert to the sign can save you from common mistakes! If you switch signs incorrectly, you could end up graphing a line in the wrong quadrant. So keeping track of your steps will lead to a clearer understanding!
