Equation's in standard form?

write each equation in standard form where a b c are integers whose greatest common factor is 1.


y = 7x+ 15?


what is standars form and how do i write something in it?

Equation's in standard form?
Standard form is y= mx + b, or using your a,b,c coefficients, ay = bx + c





By saying "whose greatest common factor is 1" is simply stating that there's no integer greater than 1 that can evenly divide each of a, b, and c





For example, this is not in standard form because each coefficient is divisible by 3:





6y = 9x + 12





However if you divide it by 3 to get the following:





2y = 3x + 4





This is now in standard form. Even though 2 divides 2 and 4, it doesn't divide 3, and you can't simplify this equation any further.





HTH! :-)





PS -- yes, y = 7x+ 15 is already in standard form
Reply:Did your instructor give you an example of standard form?


y = 7x+ 15 is one standard form (y = mx + b)


Another is ax + by = c, or


-7x +y = 15.


Yet a third standard form is


ax + by + c = 0, or


-7x + y - 15 = 0


One more:


y = a + bx + cx^2 + .....


y = 15 + 7x
Reply:Please refine your question. I'm not sure what you want.





Do you want and equivalent equation where


ay = bx + c where a,b,c are relatively prime?
