Well just looking at the points itself, the point (0,2) is the y intercept.. and the only answer choice you have with 2 as the y intercept is C.
Part A:
To get the interest of 1 year
Multiply 20,000 by 5% or 0.05
You get $1,000
Thats the amount for 1 year, now to get for 4 years, multiply 1,000, by 4
She pays $4,000 in interest
Part B:
If she pays it off in 2 years, instead of 4 years, she will pay an interest of $2,000, divide 4 by 2
Part C:
This is the same as part b, she saves $2,000
Hope this helps

The slope 1/2 y -intercept -2
6200 / 34000 = 0.1823....multiply by 100 to get ur percent
0.1823 * 100 = 18.23 rounds to 18% <=
6b<42
b<7
4b+12>8
4b>-4
b>-1
b>-1 or b<7
