The high temperatures for several days are shown in the table. which answer describes the average rate of change from day 3 to day 5?

day high temperature (degrees)
1 67
2 63
3 59
4 58
5 53

a. -4
b. -2
c. -6
d. -3

  D.  -3

Step-by-step explanation:

The temperature changes from 59 to 53 in those two days, so the average rate of change is ...

  (change in temperature)/(change in days) = (53 -59)/(5 -3) = -6/2

  = -3 . . . . degrees per day

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
