(3,6) (5,3)
(x1,y1)(x2,y2)
The slope equation is: y2-y1
---------
x2-x1
Replace with numbers: 3-6/5-3
Minus 3 and 6 is equal to -3
Minus 5-3 is 2
So the fraction is -3/2 (no need to divide because you can't simplify it)
So the slope is -3/2
For the equation you have to replace the letters by 0's
3×0-2y=6
Times 3 and 0
0-2y=6
Now you want to get the y alone, so minus 0 from both sides
0-2y=6
-0 -0
-2y=6
Divide -2y from the 6
-2y=6
---- ---
-2 -2
y=3
The y intercept is 3 with the slope of -3/2
(x-3)(x-7)=0
x=3,7

Answer:
52 inches deeper.
Step-by-step explanation:
One way you can solve this is by using subtraction.
1 foot = 12 inches and we already have 20 inches dug. The hole needs to be 72 inches deep so we just subtract 72 by 20 to find out how much more digging they need to do. They need to dig another 52 inches.
Another way to solve this, is by using subtraction and fractions.
They need to dig 6 feet and we already have 
dug. Now you can subtract. They need to dig 
feet to reach the required depth.
The Ratios remain the Same.
