Slope intercept form is y = mx + b.....so lets solve for y
9x - 7y = -7 .....subtract 9x from both sides
-7y = -9x - 7...now we divide both sides by -7
y = 9/7x + 1 <==
Answer:
The answer that is correct is salome's answer because when u multiply by 100 you would add 2 zeros
Step-by-step explanation:
Speed = Distance / Time
given distance = 6km
time = 30 minutes = 30/60 hr = 1/2hr
speed =

Total cost: 148 x 79.5 = 11,766
7% of 11,766 = 11,766 x 7 = 82.362/100 = 823,62
so, his commision was of 823,62
