What is the slope of the line containing the points left parenthesis 1 comma 4 right parenthesis(1,4) and left parenthesis 5 com
lozanna [386]

If you know the coordinates of two points

P = (P_x, P_y),\quad Q = (Q_x, Q_y)

of two points, the slope of the line passing through them is given by

\dfrac{P_y-Q_y}{P_x-Q_x}

So, if we choose in this example

P = (1,4),\quad Q = (5,1)

The slope is

\dfrac{4-1}{1-5} = \dfrac{3}{-4} = -\dfrac{3}{4}

Step-by-step explanation:

1) Circle

Solve for area

A≈28.27cm²

d=Diameter 6cm

Using the formulas

A=πr2

d=2r

Solving for A

A=1

4πd2=1

4·π·62≈28.27433cm²

To calculate 5% of a number, simply divide 10% of the number by 2. For example, 5% of 230 is 23 divided by 2, or 11.5.
