What is the equation of the line that passes through the point (-5, -3) and has a
slope of -1

The equation of the line is y = - x - 8

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

Let us solve the question

∵ The slope of the line is -1

∴ m = -1

→ Substitute it in the form of the equation above

∴ y = -1(x) + b

∴ y = - x + b

→ To find b substitute x and y in the equation by the coordinates of

   a point lies on the line

∵ The line passes through point (-5, -3)

∴ x = -5 and y = -3

∵ -3 = - (-5) + b

→ Remember (-)(-) = (+) and (-)(+) = (-)

∴ -3 = 5 + b

→ Subtract 5 from both sides

∴ -3 - 5 = 5 - 5 + b

∴ -8 = b

→ Substitute it in the equation

∴ y = - x + (-8)

∴ y = - x - 8

∴ The equation of the line is y = - x - 8

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
