What is the equation of the given line in standard form?  Use integer coefficients.

 

 

 

A. -69x + 10y = -51

B. 69x + 10y = 51

C. 69x + 10y = -51

D. -69x + 10y = 51

 

Answer 1

y = -6.9x + 5.1

Multiply each side by 10

10y =10( -6.9x + 5.1)

Using distributive property,

10y =(10*-6.9)x+(10*5.1)

10y =-69x+51

Add -69x to both sides

69x+10y=51

Therefore,Option (B) is the correct.
