Chapter 4: Q. 126 (page 530)

Find an equation of a line containing the points $(- 4, - 3)$ and $(1, - 5)$ .

Short Answer

Expert verified

The equation of the line is $y = - \frac{2}{5} x - \frac{23}{5}$ .

Step by step solution

Step 1. Given Information.

The points are:

$(- 4, - 3)$ and $(1, - 5)$ .

Step 2. Finding the Slope.

The slope of the line is,

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Inputting the values,

role="math" localid="1647329823798" $m = \frac{- 5 - (- 3)}{1 - (- 4)}$

$= \frac{- 5 + 3}{1 + 4} = \frac{- 2}{5}$

Step 3. Equation of a line.

The point-slope form is,

$(y - y_{1}) = m (x - x_{1})$

Inputting the values,

$(y - (- 3)) = - \frac{2}{5} (x - (- 4)) y + 3 = - \frac{2}{5} (x + 4) y + 3 = - \frac{2}{5} x - \frac{8}{5} y = - \frac{2}{5} x - \frac{23}{5}$
