The equation of a line is 2(y + 1) = 10x + 3. the y-intercept of the line is , and the slope of the line is .

Slope is 5 and the y-intercept is 1/2 or (0,1/2).

Step-by-step explanation:

The equation of the line is 2(y+1) = 10x + 3. Find the y-intercept and slope by applying the distributive property and using inverse operations to write it in the form y = mx + b.

2(y+1) = 10x + 3                  Multiply 2 into each term

2y + 2 = 10x + 3                 Subtract 2 on both sides

2y = 10x + 1                        Divide by 2

y = 5x + 1/2

The y = mx + b form gives the slope m and y-intercept b. Here y = 5x + 1/2 has slope 5 and y-intercept 1/2.

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
