Work Step by Step
Solve for $y$ by subtracting $3x$ to both sides: $3x+y-3x=0-3x \\y=-3x$ This means the given equation has the same graph as $y=-3x$. This equation has: slope = $-3$ y-intercept: $(0, 0)$ To graph the given equation, perform the following steps: (1) Plot the y-intercept $(0, 0)$ (2) Use the slope to plot another point. From $(0, 0)$, move 3 units down (the rise) and 1 unit to the right (the run) to reach $(1, -3)$. Plot $(1, -3)$. (3) Connect the two points using a line to complete the graph.
