The exponent in the equation is the 5.
In y = mx + b form, the slope is in the m position and the y intercept is in the b position.
y = (m)x + (b)
y = -5 x + 5.....slope (m position) = -5....y int (b position) = 5
The answer is 5.2

you must have written the equation incorrectly
He gave 75 CDs away and that was 6% of his collection.
⇒ 6% = 75
Find 1 %:
6% = 75
1% = 75 ÷ 6 = 12.5
Find 100% (100% being his full collection):
1% = 12.5
100% = 12.5 x 100 = 1250
Answer: He had 1250 CDs before he gave some away.
