This equation follows the format y=mx+b, where m is the slope of the line and b is the y intercept. In this question, the slope of the line is -2 and the y-intercept is 5.
<em>The slope of the line is -2:</em> this means that each point is down 2 and to the right 1 of each other.
<em>The y-intercept is 5</em>: this means that the line crosses the y-axis at 5.

Answer:
2.5 gal
Step-by-step explanation:
let be x = galons of solution to be drained and replace with bleach
so, we have to substract to the current solution of bleach 0.04*120, x gallons that have a concentration of 0.04 x
and also, we have to add the same gallons of bleach to the solution, that is x
and have to obtain a final concentration of 0.06*120
we can express the problem with the follow equation:
0.04*120 - 0.04*x + x = 0.06*120
solving the equation for x:
4.8+0.96*x=7.2
0.96*x=7.2-4.8
0.96*x=2.4
x =2.5 gallons
A =-5
B=6
C=-12
So ab/c
= -5×(-12)/6
=60/6
=10
