Chapter 3: Q 3.51. (page 282)

Find the equation of a line with slope $m = - \frac{2}{5}$ and containing the point $(10, - 5)$ .

Short Answer

Expert verified

The equation is $y = - \frac{2}{5} x - 1$

Step by step solution

Step 1. Use the point-slope form

The point-slope form of an equation of a line with slope $m$ and containing the point $(x_{1}, y_{1})$ is $y - y_{1} = m (x - x_{1})$ .

Step 2. Identify the slope and the point

The slope is:

$m = - \frac{2}{5}$

The point is:

$(x_{1}, y_{1}) = (10, - 5)$

Step 3. Substitute the values into the point-slope form

$y - y_{1} = m (x - x_{1}) y - (- 5) = - \frac{2}{5} (x - 10) y + 5 = - \frac{2}{5} x + 4 y = - \frac{2}{5} x - 1$

The equation of the line is $y = - \frac{2}{5} x - 1$ .
