1/2 + 1/4 = 3/4
3/4 + 1/4 = 1
The function has a slope : m = - 2 and contains the point ( 8, 12 ).
y = m x + b
12 = ( - 2 ) * 8 + b
12 = - 16 + b
b = 12 + 16
b = 28
The slope-intercept form of the function is:
y = - 2 x + 28
Amy would have spent $22.5 on her books (assuming you meant $10 total, not $10 per book)
Answer: 170
