Question

What is linear equation to (10,-10)( -10,0)

Answer 1

The expression of the linear with the given two points (a,b) & (c,d) is :

`y-b=(d-b)/(c-a)(x-a)`

We have given (10,-10) & (-10,0)

such that a =10, b=-10, c=-10, d=0

`\begin{gathered} y-b=(d-b)/(c-a)(x-a) \\ y-(-10)=(0-(-10))/(-10-10)(x-10) \\ y+10=(10)/(-20)(x-10) \\ y+10=-(1)/(2)(x-10) \\ 2y+20=-x+10 \\ x+2y+20-10=0 \\ x+2y+10=0 \end{gathered}`

The required linear equation is x + 2y + 10 = 0

Answer : x + 2y + 10 = 0
