Question

find the equation of line joining the point 2,5 and the origin​

Answer 1

Answer:

Let the equation of the line be y=ax+b

Since the line passes through the point (0,0),

we have 0=a*0+b, or b=0

Now we have the equation y=ax

Substitute x=2 and y=5 into the equation, we have:

5=2a

Or ,

a=5/2

Thus, the equation of the line is y=5/2*x
