Question

What is the equation of the given line in standard form? Use integer coefficients.
y = -6.9x + 5.1

Choices
A. 69x + 10y = 51

B. -69x + 10y = 51

C. 69x + 10y = -51

D. -69x + 10y = -51

Answer 1

6.9 and 5.1 can be written as 69/10 and 51/10

so the equation will become

y=-69x/10+51/10

since 10 is common in the denominator in the right side. So, we can write it as

y=(-69x+51)/10

if we bring the 10 to the left side we have,

10y=-69x+51

=>10y+69x=51

Answer 2

\[y=-6.9x+5.1\]
now we have to multiple each member by 10.
\[10y=-69x+51\]
\[\boxed{\boxed{69x+10y-51=0}}\]
