The answer you are looking for is A. 8 thousands blocks, 4 tens blocks, and 6 ones blocks.
This is because the 8 is in the thousands place (which equals 8 thousands blocks), the 4 is in the tens place (which equals the 4 tens blocks), and the 6 is the ones place (which equals the 6 ones blocks).
Your slope is wrong! Your slope is going to be 3/2, or C for the first problem. Your y intercept is wrong! Your Y- intercept is actually (0, -1.3) or B for the second problem. Your equation is going to be y= 3/2x-1.3
