Write the equation in standard form Ax + By = C that passes through (4,6) and (0,0)?

First you find the slope of the line.





6-0/4-0 =3/2





Then you can find the equation using the point-slope formula.





y-y1= m(x-x1)


y-0=3/2(x-0)


y=3/2x





now to put it into standard form, you have to put the y and the x on both sides, so





-3/2x+y=0





BUT. the x must be positive soooo....





3/2x-y=0

Write the equation in standard form Ax + By = C that passes through (4,6) and (0,0)?
-3A + 2B = 0


-6A + 4B = 0


-12A+8B = 0
