Answer:
y = -1/2 x - 3 1/2
Step-by-step explanation:
points (1, -4) (3,-5)
slope = (y2-y1)/ (x2-x1)
slope = (-5--4)/(3-1)
= (-5+4) /2
=-1/2
point slope form of a line
y-y1 = m(x-x1)
y--4 = -1/2 (x-1)
y+4 = -1/2 (x-1)
if we want slope intercept form
distribute
y+4 = -1/2 x + 1/2
subtract 4 from each side
y+4-4 = -1/2 x + 1/2 -4
y = -1/2 x - 3 1/2

Answer:
The addition rule for probabilities describes two formulas, one for the probability for either of two mutually exclusive events happening and the other for the probability of two non-mutually exclusive events happening.
The first formula is just the sum of the probabilities of the two events. The second formula is the sum of the probabilities of the two events minus the probability that both will occur.
