Which of the following is a true biconditional statement? Х
A. A U. S. citizen votes if and only if the person is at least 18 years old,
B. A number is a real number if and only if it is a positive integer
C. If a figure does not have four sides, then the figure is not a square.
D. The product of two integers is odd if and only if the two factors are odd.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

you can rewrite it as follows: 2(24+30)
