finding the equation from graph..

[tarek like math]

$(y-3)/(x-2)=(y-8)/(x-5)=Slope(constant)$

[Mehfuj Zahir]

The equation through two points \[(x_{1},y_{1}) and (x_{2},y_{2})\]
is \[\frac{x-x_{1}}{x_{1}-x_{2}}=\frac{y-y_{1}}{y_{1}-y_{2}}\]
then rest is yours two points are given now find the equation

You have to be given enough points to be sure about the graph. From only two points, you can't be sure about the equation. For example, $(2,3)$ and $(5,8)$ lie on the line $5x-3y-1=0$ also on the circle with center $(6,4)$ and radius $\sqrt{17}$ and on infinitely many equations.

You have to be given enough points to be sure about the graph. From only two points, you can't be sure about the equation. For example, $(2,3)$ and $(5,8)$ lie on the line $5x-3y-1=0$ also on the circle with center $(6,4)$ and radius $\sqrt{17}$ and on infinitely many equations.

For example , if you are given three points ,you can always draw a circle(sometimes with center at point of infinity ) and given five points , you can always draw a conic.
