40 points When Anthony left his house in the morning, his cell phone battery was partially charged. Let BB represent the charge remaining in Anthony's battery, as a percentage, tt hours since Anthony left his house. A graph of BB is shown below. Write an equation for BB then state the slope of the graph and determine its interpretation in the context of the problem.

Using the slope equation Y2-Y1/X2-X1 we can solve the equation. The equation will be written as y=mx+b. b is the starting point so it will equal 20

10-15/4-2 = -5/2 < slope

the equation would be BB = -5/2(x) + 20

hope this helps.

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
