On Monday, water was pumped out of the pool at a constant rate, starting at 12:00 p. m. At 12:15 p. m., the water in the pool was 45 inches deep.
At 12:35 p. m., the water in the pool was 41 inches deep.
Part B - Write an equation that represents y, the depth of the water (in inches), after x minutes.
y = 48 +0.22
y=41 – 0.23
y=45 -0.2x
y=45 +0.2x
y = 41 +0.2x
y = 48-0.2x

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
