Seven values on the number line above are marked with letters. Match the opposites.

Step-by-step explanation:

The opposite of any number (let's call it "x") is a number which, if added to x, results in 0.

Typically is -x, because x + (-x) = x - x = 0

Knowing these, let's see the values that are marked:

A = -7

W = -5

C = -3

B = 1

P = 3

X = 5  

E = 7

The opposite of 7 is -7, so A and E are opposites.

The oposite of 5 is -5, so X and W are opposites

The opposite of 3 is -3, so P and C are opposites.

The opposite of 1 is -1, but -1 is not marked.

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.
