6-(-5)

Step-by-step explanation:

Given :

The given expression is solve by some fixed rules of addition and subtraction of such numbers.

The minus sign outside the bracket changes the sign inside the bracket to opposite.

The sign during adding and subtraction is taken as:

The sign of greater value is taken always in addition or subtraction.

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.
