Can anyone show me how to do this question please.
thanks
thanks
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
Original post by 2-ethylbut-1-ene
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
Find the gradient
Then use one of the points to find the equation
Can somebody please do this step by step, I'm stuck!!

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
Do you know the gradient of AD

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

Which bit do you think is incorrect?

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