Using a compass, jane draws a circle on her paper with a radius of 2.5 inches. what is the area of the circle?
a) 15.7 in2
b) 19.625 in2
c) 24.649 in2
d) 61.6225 in2

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.

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
