If you use a pair of x- and y- coordinates (x, y) to represents a point in a two-dimensional cartesian coordinate a system how would you represent a point in three-dimensional cartesian coordinate system? a.(x, y,z) b.(w, x,y) c. x,y, z d.(x, y,v)

A (x,y,z) I don't know how to explain it really well but i learned it when i was programming

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.
