An equation in the system is y = x + 1. what is the other equation in the system if the solution is only at (0, 1)? a. x − y = 1 b. 2x + 2y = 4 c. x + y = 0 d. x + 2y = 2

D

Step-by-step explanation:

two data sets with the same median will not have the same varaibility

step-by-step explanation:

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.
