What is the equation of the given line in standard form using integers coefficients y equals -1.7 x + 8.5

If you want integer coefficients only, multiply the equation of the line by 10.  I'm assuming you accidentally left off the "= 0" at the end:  -1.7x + 8.5 = 0.

If that's the case, then  multiplying the whole equation by 10 results in -17x + 85 = 0.

Here you have only integer coefficients.

The answer is something i don’t know

Move the decimal behind it
