Question

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

Answer 1

Since we want integer coefficients, we should get those decimal values to whole numbers. To do this, we multiply both sides by 10

y = -6.9x + 5.1
10*y = 10*(-6.9x + 5.1)
10y = 10*(-6.9x) + 10*(5.1)
10y = -69x + 51

Are you following so far?

Answer 2

Since you have y=-6.9x+5.1 and standard form is Ax+By=C. You have to add 6.9x so you would have 6.9x+y=5.1
