Answer:

y = -0.5x - 3.5

Explanation:

Take two points: (1, -4), (3, -5)

Find slope:

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

$\rightarrow \sf slope \ (m) : \dfrac{-5-(-4)}{3-1} = -\dfrac{1}{2}$

Equation:

$\sf y- y_1 = m (x - x_1)$

$\rightarrow \sf y- (-4) = -\dfrac{1}{2} (x -1)$

$\rightarrow \sf y+ 4 = -\dfrac{1}{2} x + \dfrac{1}{2}$

$\rightarrow \sf y = -\dfrac{1}{2} x + \dfrac{1}{2} - 4$

$\rightarrow \sf y = -0.5 x -3.5$
