Answer:
option b.
Equation of line passing through ( 3, 4) and ( - 1 , 4) :
[tex](y + 4) = -2 (x-3)[/tex]
Step-by-step explanation:
Step 1 : Find slope.
[tex]slope, m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 -- 4}{-1-3} = \frac{8}{-4} = -2[/tex]
Step 2 : Equation of line.
[tex]( y -y_1) = m (x -x_1) \ , \ where\ (x_1, y_1) = (3, -4) \ , \ m = -2[/tex]
[tex](y + 4) = -2 (x-3)[/tex]
