A meteorologist used the expression below to describe how the temperature changed. Negative 5 + (negative 4) Which statement could describe how the temperature changed? The temperature was –5 degrees, then it increased 4 degrees.

The temperature was –5 degrees, then it decreased 4 degrees.

The temperature was 5 degrees, then it increased 4 degrees.

The temperature was 5 degrees, then it decreased 4 degrees.

b

Step-by-step explanation:

The temerture was -5 degrees, then it decreased 4 degrees.

your answer is d 2,500

step-by-step explanation:

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
