Igive brainist angela bought gifts for her friends, and each gift cost $10. let y represent the total cost and x represent the number of gifts. write an equation to represent the proportional relationship between the total cost and the number of gifts she bought. y = 9x y = 10x y = one-tenth x y = one-ninth x

y = 10x

Step-by-step explanation:

you can multiply $10 by x ( x = number of gifts for friends ) and your answer would be

y = 10x

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.

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
