const2013 [10]

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

\spadesuit\; Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}

Given Points are (1 , 7) and (-4 , -8)

here x₁ = 1 and x₂ = -4 and y₁ = 7 and y₂ = -8

\spadesuit\; Slope(m) = \frac{7 + 8}{1 + 4} = \frac{15}{5} = 3

9966 [12]

Answer:

11 °F

Step-by-step explanation:

The problem explains the last temperature is -7 °F and in the process the temperature dropped 18 °F, we can then make a simple equation for the starting temperature

ST-18°F=FT

ST: starting temperature

FT: final temperature

ST-18=-7

ST=-7+18=11 °F
