In two or more complete sentences describe the process in writing the equation of a line given two points.

Let () and () be two points belonging to a line, then from these two points we can find the equation of the line of the form

y = mx + b

where m is the slope and b is the cut point with the y axis.

the slope of the line is found with the following formula.

To find b substitute and in the equation and clear b. (You can also replace and )

After finding the value of m and b, you already have the necessary parameters to write the equation of the line y = mx + b

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
