Transcript text: pts) 6) Write the equation of the given line in slope intercept form.
Solution
Solution Steps
Step 1: Find two points on the line
The line passes through the points $(0, -3)$ and $(-3, 0)$.
Step 2: Calculate the slope
The slope of the line is given by $m = \frac{y_2 - y_1}{x_2 - x_1}$. Using the points $(0, -3)$ and $(-3, 0)$, we have $m = \frac{0 - (-3)}{-3 - 0} = \frac{3}{-3} = -1$.
Step 3: Determine the y-intercept
The y-intercept is the point where the line crosses the y-axis. From the graph, this occurs at $(0, -3)$, so the y-intercept is $b = -3$.
Step 4: Write the equation in slope-intercept form
The slope-intercept form of a linear equation is $y = mx + b$. We found $m = -1$ and $b = -3$. Therefore, the equation of the line is $y = -x - 3$.
