Answer:
The line passing through the given points is:
in its slope-intercept form
Step-by-step explanation:
Start by finding the slope of the segment that joins the two given points using the slope formula:
which for our case renders:
Now we can find the y-intercept by using any one of the given points in the general slope-intercept form of a line with this slope:
Therefore, the equation of the line becomes:
Answer:
74 weeks
Step-by-step explanation:
Given :
Let x = number of weeks
Gallon A:
Capacity = 666
Leak rate = 4 gallons per week
666 - 4x
Gallon B:
Capacity = 888
Leak rate = 7 gallons per week
888 - 7x
666- 4x = 888 - 7x
666 - 888 = - 7x + 4x
-222 = - 3x
x = 222 / 3
x = 74
After 74 weeks
