Find 41
41 (+) 29 (mod 8)​

Step-by-step explanation:

first...

41+29=70

:. 70mod 8 =

70÷8 = 8 remainder 4

when dealing with mod all you need is the remainder

so your answer is 4

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.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
