Write the equation of the line that goes through the point (2, -1) and has a slope of
-3.

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = - 6 + c ⇒ c = - 1 + 6 = 5

y = - 3x + 5 ← equation of line

answer: the answer is   3. "sometimes".

step-by-step explanation:   we are familiar with the theory of probability and the popular rules we use in the theory.

for example, we have the rule that- if the two events are independent, the the probability of their intersection is equal to the product of their probabilities.

now, given that the two events a and b are independent of each other. so,

p(a and b) = p(a)×p(b).

also, p(a)> 1/2   and   p(b)> 1/2.

therefore,   p(a and b) > 1/2× 1/2=1/4.

i.e., p(a and b)> 1/4. so, it may be greater than 1 because 1> 1/4.

thus, p(a and b) is sometimes greater than 1.
