Your answer would be (3,0)
In y = mx + b form, the slope can be found in the m position and the y intercept can be found in the b position.
y = mx + b
y = 2x + 15
slope(m) = 2 and y int (b) = 15
The initial amount is the y intercept, which is 15. The rate of change (the slope) is 2
example :
baskets picked in 1 hr :
y = 2(1) + 15
y = 2 + 15
y = 17
baskets picked in 2 hrs :
y = 2(2) + 15
y = 4 + 15
y = 19
so the slope ( rate of change) is basically saying for every hr of picking, you pick 2 baskets...so your picking 2 baskets per hr.
The y intercept (15) is telling us that they already had 15 baskets to start with.
The graph went left 1 and up 6. You could complete the square to find out or just graph it!
Hope this helps!
Hello from MrBillDoesMath!
Answer:
Choice C
Discussion:
We interrupt this Question by a special commercial announcement..... Consider the simpler case of f(x) = x^2. If we shifted this curve 4 units to the right, then the point x is mapped to x-4. (f(0) = 0 on the original curve; now f(x-4) = 0 when x =4. So shifting to the right replaces x by x-4.) Now back to our regular TV programming....
Shifting f(x) = x^2 -3x - 2 four units to the right produces
g(x) = f(x-4) = (x-4)^2 -3(x-4) -2
This is choice C.
Thank you,
