Question

find the equation of the straight line that passes through the point (-5,-7) and has a slope -1/2
​

Answer 1

Step-by-step explanation:

$y = mx + c \\ - 7 = ( - \frac{1}{2} )( - 5) + c \\ - 7 = \frac{5}{2} + c \\ c = - \frac{19}{2} \\ y = - \frac{1}{2} x - \frac{19}{2} \\ y = \frac{ - x - 19}{2} \\ 2y = - x - 19$
