Answer:
-7
Step-by-step explanation:
y=3x-7
x=0 ⇒ y= 3*0-7= -7
Option B is the correct answer because you start with 15 gallons (y-intercept), and the car consumes or decreases at 0.03 gal/per mile (your slope or m).
4y + 228= 352
-228 -228
4y= 124

4 4
y=31
Add the ratio to get total shares: 4 +1 = 5
Divide the total amount to share by the total shares:
150 / 5 = 30
Now multiply each set of shares by that:
4 x 30 = 120
1 x 30 = 30
120-30 = 90 more
