Answer:
f(x) = 1/3x + 1
Step-by-step explanation:
slope-intercept form is
f(x) = mx + b
so just put the points in and you have:
f(x) = 1/3x + 1
also b stands for the y-intercept so if you look at your point (9,1) than your y-intercept would be 1.
hope I could help!!
If the first increase was 50%, that means that the price between the first and the second increase is 150% of the original. And as you need 6 (which is 4*150%) times the original, the price was increased for 450%. So, the last peecent increase is
