(0,40)(4,120)
slope = (120 - 40) / (4 - 0) = 80/4 = 20
y = mx + b
slope(m) = 20
(0,40).....this means we have a y int of 40
so ur equation is : y = 20x + 40......this basically means the fee is $ 20 per day....and the fixed amount is $ 40 <===
I believe it is <span>b)the square of the sum of 2 times x and 5</span>
The answer is 8, 9, 10, 11
