Write the sentence as a proportion. Then determine whether the proportion is a true proportion. one and five tenths is to three as two and one tenths is to seven

The proportion is

Is the proportion true?

Note 15/100 = 0.15 and 21/100 = 0.21

0.15:5::0.21:3

0.15/5 = 0.21/3

0.03 = 0.07

This is NOT a true proportion

lol

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.
