<span>Found a similar problem with the given table.
Elapsed time
(Minutes) 0 10 20 30 40 50 60 70 80 90
Rate
(gallons / minute) 42 40 38 35 35 32 28 20 19 10
Because the interval is every 10 minutes, we will use 10 and multiply it to each rate and get the sum total.
42*10 + 40*10 + 38*10 + 35*10 + 35*10 + 32*10 + 28*10 + 20*10 + 19*10 + 10*10
420 + 400 + 380 + 350 + 350 + 320 + 280 + 200 + 190 + 100
2,990
There will be a total of 2,990 gallons in the tank after 90 minutes. </span>
This is how I did it:

use distribution

use addition

use addition and subtraction

use division


So your answer is

Answer:
<h2>
<u>
y = -3x - 8</u></h2>
Step-by-step explanation:
The equation of the line that passes through the point <em>(x₁, y₁)</em> and has a slope of <em>m</em> in point-slope form is: y - y₁ = m(x - x₁)
m = -3
(-4, 4) ⇒ x₁ = -4, y₁ = 4
Therefore:
y - 4 = -3(x - (-4))
<u>y - 4 = -3(x + 4) </u><u> </u> ← point-slope form
y - 4 = -3x - 12 {add 4 t both sides}
<u>y = -3x - 8 </u> ← slope intercept form
