**Solution**

1.A={8,4}

C={8,-5}

3.7.2 units

1.A={-4,4}

C={8,-5}

2.y=1-3x/4

3.7.2 units

Hi Madhubala,

You got almost all answers correct! For the second part, I see that you accidentally found the equation of AC instead of BD. By the way, the equation of line AC is indeed y = 1 – 3x/4 or, 4y = 4 – 3x.

Hi Madhubala,

I am glad you realized that the second part was asking to find the equation of line BD (and not AC). Now, if slope of AC is -3/4 (as you have correctly found earlier), what will be the slope of line BD? What is the relational between slopes of any two perpendicular lines? Pls check your work. Hope it helps!

Cheers,
