Susie wants to write equations in the form y=mx+b for the lines passing through point r that are parallel and perpendicular to line s. first she finds the slope of line s and line v to be −23 and the slope of line t to be 32. point r is located at (2,2). which step could be used to find the y-intercepts?

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.
