graph the line.\ny = - 3x

Explanation:

Step1: Find the y - intercept

The equation $y = - 3x$ is in slope - intercept form $y=mx + b$, where $m$ is the slope and $b$ is the y - intercept. Here $b = 0$, so the line passes through the origin $(0,0)$.

Step2: Find another point using the slope

The slope $m=-3=\frac{\Delta y}{\Delta x}$. Starting from the origin $(0,0)$, if we let $\Delta x = 1$, then $\Delta y=-3$. So another point on the line is $(1,-3)$.

Step3: Plot the points and draw the line

Plot the points $(0,0)$ and $(1, - 3)$ on the coordinate plane and draw a straight line passing through them.

Answer:

Plot the points $(0,0)$ and $(1,-3)$ and draw a straight - line through them.
