The equation is y = -3x - 4, which is in slope-intercept form. The y-intercept is -4 and the slope is -3. Using the slope and y-intercept, we can plot two points and draw a line through them. Another way to graph the equation is to start with the y-intercept and then use the slope to find another point. Either way, the graph should look like a straight line with a negative slope. Only choice B accurately represents this. The equation is in slope-intercept form (y=mx+b), where m is the slope and b is the y-intercept. The slope is 1/2, meaning for every increase of 2 in the x-coordinate, the y-coordinate increases by 1. The y-intercept is -3, meaning the line passes through the point (0,-3). Plotting these two points and drawing a straight line through them gives us the graph of the linear equation. Choice B correctly shows this line.
