2. Original A ABC: A(1,2), B(3, 4), C(3, 2) First image: A A'B'C:A' (2,21), B'(4, 23), C '(2, 23) Final image A A"B"C":
A"(21, 3), B"(1, 1), C "(21, 1)
What are rules for these images

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

7 is the median   7.875 is the mean
