I say it’s c.150 because 6 hours is 300 then 5 hours is 250 so you’re subtracting 50 for 1 less hour, so 4 hours would be 200 that makes 3 hours 150
got it? hope that’s not too confusing

The equation of the line passing through the points (-2,0) and (0,-4)
![\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%20-%20y1%7D%7Bx%20-%20x1%7D%20%20%3D%20%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)

![x - 2y = 4](https://tex.z-dn.net/?f=x%20-%202y%20%3D%204)
Option B
x minus 2 y = 4 and 2 x + y = negative 4
