Devin belongs to the rock climbing gym and pays $ 42 each month. He still needs to pay an additional $6 for each lesson. Jared is not a member and has to pay $ 17 for each
lesson. How many lessons do they need to take to spend the same amount of money?

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.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
