John's function : y = 3.5x - 4
Penny's function : y = 3x + 4
C. John's function has a greater rate of change, because 3.5 > 3
I got 20,737 but I could be wrong so I will attach my algorithm and work.
Answer:
-.5
Step-by-step explanation:
The simpliest form is 71/10, the fraction
Step-by-step explanation:
Since this isn't a really small (1/1000000000) or really big (like the radius of the earth) number you don't need the standard notation, so the fraction 71/10 is the simpliest because there is only a decimal, so it can be a fraction of ten.
If you are given 2 points, it's easy to find the slope.
(8, -6)
(3, -2)
slope = (y₂ - y₁) / (x₂ - x₁)
slope = (-2 + 6) / (3 - 8)
slope = (4) / (-5)
m = 4/-5 or -5/4 or
