Well just find the two means
The first on would be 25
The second one would be 25
So the answer is stay the same
Hope I helped brainlest???
Minutes(m) Cost
0 20
10 22
20 24
50 30
slope formula:
m = (y1 - y2) / (x1 - x2)
m = (20 - 22) / (0 - 10) = -2/-10 = 1/5 or 0.20
y = (1/5)(x) + 20
The rule that describes Amy's monthly cost is:
m = 1/5x + 20 or m = 0.20x + 20
Where x is the number of minutes spent on the call.
Step-by-step explanation:
+9x-4x=83-1
5x=82
or,x=82/5
or,=16.4
