Slope Intercept F2Ed6C
1. **State the problem:** Convert the linear equation $2x + 5y = 7$ into slope-intercept form.
2. **Recall the slope-intercept form:** The slope-intercept form of a line is given by:
$$y = mx + b$$
where $m$ is the slope and $b$ is the y-intercept.
3. **Isolate $y$ in the given equation:** Starting with
$$2x + 5y = 7$$
subtract $2x$ from both sides:
$$5y = -2x + 7$$
4. **Divide both sides by 5 to solve for $y$:**
$$y = \frac{-2x}{5} + \frac{7}{5}$$
5. **Interpret the result:** The equation in slope-intercept form is
$$y = -\frac{2}{5}x + \frac{7}{5}$$
which means the slope $m = -\frac{2}{5}$ and the y-intercept $b = \frac{7}{5}$.
This form is useful for graphing and understanding the behavior of the line.
