Question

Determine which ordered pair is a solution of y=-5x-1 a. (9, –2) b. (5, 24) c. (–1, 6) d. (–4, 19)

Answer 1

(x, y)

y = -5x - 1

a. (9, -2) → x = 9, y = -2

-2 = -5(9) - 1

-2 = -46 FALSE

b. (5, 24) → x = 5, y = 24

24 = -5(5) - 1

24 = -26 FALSE

c. (-1, 6) → x = -1, y = 6

6 = -5(-1) - 1

6 = 4 FALSE

d. (-4, 19) → x = -4, y = 19

19 = -5(-4) - 1

19 = 19 TRUE

Answer: d. (-4, 19)
