Which of the following represents "the difference between a number and eight is twenty-two"?
8 - n = 22
n - 8 = 22
8 - 22n

The Answer is N - 8 = 22

this is because the question ask the difference of a number and eight is twenty-two, which means a number (N) comes first before the difference ( - ) is  eight (8) is (=) twenty two (22) following this order gives the answer above in bold.

Step-by-step explanation:

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.

its an acute right triangle
