Parallel Line 345070
1. **State the problem:** Find the equation of the line in slope-intercept form that is parallel to the line $2x + 5y = 10$ and has the same $x$-intercept as the line $3x + 4y = 15$.
2. **Find the slope of the given line $2x + 5y = 10$:**
Rewrite in slope-intercept form $y = mx + b$:
$$5y = -2x + 10$$
$$y = -\frac{2}{5}x + 2$$
So, the slope $m = -\frac{2}{5}$.
3. **Find the $x$-intercept of the line $3x + 4y = 15$:**
At $x$-intercept, $y=0$:
$$3x + 4(0) = 15 \implies 3x = 15 \implies x = 5$$
So, the $x$-intercept is $(5, 0)$.
4. **Write the equation of the line parallel to $2x + 5y = 10$ passing through $(5,0)$:**
Parallel lines have the same slope, so slope $m = -\frac{2}{5}$.
Use point-slope form:
$$y - y_1 = m(x - x_1)$$
Substitute $x_1=5$, $y_1=0$:
$$y - 0 = -\frac{2}{5}(x - 5)$$
Simplify:
$$y = -\frac{2}{5}x + 2$$
5. **Final answer:**
The equation in slope-intercept form is
$$y = -\frac{2}{5}x + 2$$
