Answer:

The answer to your question is letter A

Explanation:

Process

1.- Find two points of the line

A (1, 4) B ( -1, 5)

2.- Find the slope of the line


m = (y2 - y1)/(x2 - x1)


m = (-5 - 4)/(-1 - 1)


m = (-9)/(-2) = (9)/(2)

3.- Find the equation of the line

y - y1 = m(x - x1)

y - 4 = 9/2(x - 1)

2y - 8 = 9x - 9

9x - 2y = - 9 + 8

9x - 2y = - 1

4.- Convert the equation to a inequality,

9x - 2y ≤ -1
