Which graph represents a function with direct variation?

BUT WHERE IS THE GRAPH

That means that the graph of a function with direct variation has these features: It is a straight line: because the slope is the ratio y/x = k. It passes through the origin (0,0): because y = kx = k (0) = 0.That means that the graph of a function with direct variation has these features: It is a straight line: because the slope is the ratio y/x = k.

Step-by-step explanation:

mark me as brainliest

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.

b, i believe, but not sure.
