This is a linear relationship. The slope-intercept form of the linear equation is:
Where,
- m is the rate of change (positive if increasing rate and negative if decreasing rate)
- c is the y intercept, or the initial value
<u><em>Rate of change is 2.5 quarts per minute (it is decreasing so m is -2.5)</em></u>
<u><em>Initial value is 50 quarts, so c is 50.</em></u>
Plugging in the values we get 
.
Changing variables to w instead of y and t instead of x, gives us,
. Where w is warts of water left in the tub and t is the time in minutes.
There is no viable solution when t=30 because at t=20, w=0 (
). It means after 20 minutes, there is no water left. So t=30 minutes doesn't make sense.

Step-by-step explanation:
Ordering the numbers from greater to the lesser we would get that:
3 > 1 3/4 > -0.5 > -3.
Knowing that, we can proceed to represent each number on the number line, which is attached!
<u>First, find the perpendicular slope</u>
y = 0.3x + 6 ⇒ m = 0.3 = 
perpendicular slope = 
<u>Next, input</u> the point (x₁, y₁) and slope (m) into the Point-Slope formula
y - y₁ = m(x - x₁)
y - (-8) = (x - 3)
y + 8 = 
+ 10
y = + 2
(9 - 7 X 3 + 4 )²

First look at the Brackets
There are no indices in the brackets
There is no division in the brackets
There is a Multiplication in the brackets 7 x 3
For the answer
(9 - 7 x 3 + 4)²
Brackets
Multiplication 7 x 3 = 21
(9 - 21 + 4)²
Addition -21 + 4 = -17
(9 - 17)²
Subtraction 9 - 17 = -8
-8²
Now start again once the brackets are gone
-8²
Indices
-8 x -8 = 64
