It is 5 degrees outside and the temperature is expected to drop 4 degrees each hour for the next 3 hours. if this prediction is correct, what will the temperature be in 3 hours?

-7

Step-by-step explanation:

5-4-4-4=-7

(-1,-0.5)

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
