Dude I dont understand it I would leave if i knew how
Step-by-step explanation:
Answer:
at 0 the amount is 5
1 is 7.5
2 is 10
3 is 12.5
the initial value is the y intercept when the value ox x=0
the initial value is 5
the rate of change is the total change of a function of the out put (y) divided by the change of the input (x)
f(x2)-f(x1)/x2-x1
10-7.5/2-1
2.5/1=2.5
or m=y2-y1/x2/x1=10-7.5/2-1=2.5
y=2.5x+5
