(5,22.45),(7,25.45)
slope = (25.45 - 22.45) / (7 - 5) = 3/2 or 1.5
y = mx + b
slope(m) = 1.5
use either of ur points...(5,22.45)...x = 5 and y = 22.45
now sub and find b
22.45 = 1.5(5) + b
22.45 = 7.5 + b
22.45 - 7.5 = b
14.95 = b
so ur equation is : y = 1.5x + 14.95.......this means that each quart of oil costs $ 1.50 and the labor fee costs $ 14.95
The answer is B because if you have 10000 hours you subtract by 3000 and it’s equals b
We will use the formula of discount % to find the selling price...!

Hello,
To write 170 as a fraction ,you have to write 170 as the numerator and put it over 1 for the denominator.
After that, you now multiply numerator and denominator by 10.
170 = 170/1 (x 10) = 1700/10
The answer then is:
170 as a fraction<span> equals </span><span>1700/10
