Answer:
y = -4x -2
Step-by-step explanation:
The slope is given by the formula ...
m = (y2 -y1)/(x2 -x1)
m = (-10 -10)/(2 -(-3)) = -20/5 = -4
__
The y-intercept is given by ...
b = y1 -m(x1)
b = 10 -(-4)(-3) = 10 -12 = -2
Then the slope-intercept equation is ...
y = mx +b
y = -4x -2
Depends to what time (month, days, weeks) I'll assume annually which would be 150$ a year
20 × 10fl ounces = 200 fl ounces
1 gallon= 128 fl ounces
200 fluid ounces equals about 1.56 gallons so
you would need to buy about two gallon bottles.
