Answer:
B, y = 4x + 1
Step-by-step explanation:
to get it into y- intercept form we need to write it in the form y = mx + b
-8x = 2 - 2y, move 2y to the other side and -8x to the other side they both become positive.
2y = 8x + 2, dividing each by 2 
yields y = 4x + 1
Hope this helps

To solve this, just take $80 and subtract her amount of money she has now, which is 8. $80-$8=$72
She needs $72
