The answer is C.

Step-by-step explanation:

In the graph above, it is a positive gradient so option A and B cannot be applied.

Next you have to look at the y-intercept where the line touches the y-axis so -1 is the y-intercept.

The slope-form equation is y = mx + b where m represents gradient amd b is y-intercept :

Option A,

- 2x - y - 1 = 0

$y = - 2x - 1 \: (incorrect \: m)$

Option B,

2x + y - 1 = 0

$y = - 2x + 1 \: (incorrect \: m \: and \: b)$

Option C,

2x - y - 1 = 0

$y = 2x - 1 \: (correct \: m \: and \: b)$

step-by-step explanation:

i found the life tables for the year 2012.

life table of males at age 30. probability of dying between ages x and x+1

total population:

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old.

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
