Y = -1/3x + 5....slope here is -1/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So ur perpendicular line will have a slope of 3.
y = 3x....has a slope of 3, so this is perpendicular.
3x - y = 2.....y = 3x- 2.....has a slope of 3 and is therefore perpendicular
3x - y = 6.....y = 3x - 6...has a slope of 3 and is perpendicular

<em>Here is the whole work I did, so you can understand how to get the answer!</em>
<em>1. Divide 374 by 7</em>
374 ÷ 7 = 53.4
<em>2. Round to nearest whole number</em>
Since 4 in the tenth place is closer to zero than one, we round it down and get 53.
Oh the thing surrounding the whole work I did is just a spacer to make the answer not boring!
This is a question of proportionality. However, it is not direct proportionality as it is expected that as the number of tractors increases, the work is finished faster as opposed to fewer number of tractors. This is referred to as inverse proportionality.
Therefore;
6 tractors ----- 10 days
18 tractors --- x days
Then,
x = (6*10)/18 = 10/3 days = 3 days, and 8 hours.
This means that 18 tractors will take 3 days and 8 hours to collect the same harvest.
