The temperature dropped 15 degrees in an hour. If the starting temperature was 10 degrees, what was the final temperature?

If we're talking about the final temperature in 1 hour, then the final temperature would be -5 degrees. 10-15= -5.

the correct answer is 1: 2

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
