Hello...could someone help me out?? ty :)

A

Step-by-step explanation:

Always start by finding the slope when you're given two points! (This means that we can rule out C and D.) The equation for slope is

You can remember this by thinking about it being rise over run, or the distance you go up or down divided by the distance you go across. This means that answer choices B and D are incorrect.

Next, what do we plug into slope-intercept form to get the y-intercept? The slope, and one other point.

y = mx+b

You can see that if we were to plug in m, x, and y, we'd only have b left, and we could solve!

This means that choice A is correct.

ab: 2 n83b8eb7ebi. 8e yen in

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.
