You know the coordinates of B and C

The fact that AB = BC means you can find A

Given you have A and D you should be able to find the equation

The gradient, (m), of abc is -1/2. Therefore, the gradient of DA will be 2, as they are perpendicular lines
What makes you think that the lines are perpendicular?

yes I already know that information. But I don't know how to work out the equation, so if you don't mind can you explain it for me please?

When you have two points on a line

Then use one of the points to find the equation

I have told you ... And you said that you understood

Let's try again

Do you know the coordinates of B
Do you know the coordinates of C
Have you found the coordinates of A

Coordinates of b I think are 0,5
cooridnates of c Idk
cooardinatws of a idk

could you specifically tell me them And do the equation. I need to see it to understand it.

I will not solve the problem

You need to think for yourself in order to understand

B is indeed (0,5)

What is y at point C? Use that to find the x co-ordinate of C

The y intercept but then usually that means that the entire answer went wrong somewhere.
