For all just put them together in x and y. For example, f(2)=-2 would be (2,-2). f(1)= 1 would be (1,1).

The answer is 3/9 or 1/3 in its simplest form

**Answer:**

<u>** 2y + 3x = 3**</u>

**Step-by-step explanation:**

The standard form of equation of a line is expressed as;

y = mx+c

m is the slope

b is the intercept

We are to find the equation of a line passing through the points (-3,19) and (6,-2)

**First get the slope**

m = y2-y1/x2-x1

m = -2-19/6-(-3)

m = -21/9

m = -7/3

Get the y- intercept b;

Substitute the coordinate (6, -2) and m = -7/3 into the expression y = mx+b and get b;

-2 = -7/3(6) + c

-2 = -7/2 + c

c = 7/2 - 2

c = (7-4)/2

c = 3/2

**Substitute the slope and intercept into the formula**

y = mx+b

y = -7x/2 + 3/2

Multiply through by 2;

2y = -7x + 3

2y + 7x = 3

**Hence the required equation is**<u>** 2y + 7x = 3**</u>

**Answer:**

**Therefore work required to pump out of all liquid is 81p ft-lb.**

**Step-by-step explanation:**

**Given that,**

A rectangle tank dimension is 3 feet long, 6 feet wide and 3 feet tall.

The density of the liquid in the rectangular tank is p.

The **volume** of water of strip is

=long ×wide ×

=(3 ×6 ×) ft³

**Force is** = (3 ×6 ×)×p pound

**Total work done **

** **

=81p ft-lb

**Therefore work required to pump out of all liquid is 81p ft-lb.**
