Question

What is the equation of straight line ?
Give its proof too

Answer 1

The equation of a straight line is \(\rm y = mx + b\). I don't know of the proof, but I do know about the intuition.

Answer 2

Sorry @ParthKohli its not it ... its the slope intercept form .... whats the original equation

Answer 3

y-y1=m(x-x1)

that equation?

Answer 4

y=x ? i dont know any other equations for straight lines :P

Answer 5

Oh, you may rearrange it into different forms.\[\textbf{point slope: }\rm y - y_1 = m(x - x_1) \]

Answer 6

Do you need the standard form?\[\rm Ax + By = C\]

Answer 7

yes i need the stand form .... plz tell me

Answer 8

Yes, that was the standard form!

Answer 9

what is the standard form vs whatever else?

Answer 10

Note that \(\rm A,B,C\) are constants.

Answer 11

THANKS BRO
