Question

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

A. -69x + 10y = -51
B. 69x + 10y = 51
C. -69x + 10y = 51
D. 69x + 10y = -51

Answer 1

Ax+By=C --> standard form

so rearrange your given equation into standard form first then I'll tell you what you need to do next :)

Answer 2

I'm really not sure how to do this problem...

Answer 3

right now your equation is in the form y=mx+b

change it to Ax+By=C
so y = -6.9x + 5.1 will be 6.9x+y=5.1 by adding both sides by 6.9x

then your question says " integer coefficients." which means that all the coefficients should be whole numbers.. do this by multiplying each term by 10

therefore you will have : 69x+10y=51

is it clear?

Answer 4

sorry late repz.
