Answer:
See picture attached.
Step-by-step explanation:
Start with the y-intercept of -2 and plot that on the graph. Then, use the slope of 1/2x to plot more points to help you draw the line. Remember rise over run. Go up one from the y-intercept and right two. If you need to, you can also go down one and left two.
Hope this makes sense.
6, 12, 18

First, you need to get to one gallon, which is 37.20 divided by 12. (3.1)
Divide that number by four, which is: 0.775, or 0.78 rounded up to the nearest hundredth.
Hope that helped.
Step-by-step explanation:
12. 136/300
=52%
13.45/300
=15%
slope = - 
calculate the slope m using the gradient formula
m= (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 3, 6)
m = 
= 
= -
