Question

Write y = –0.5x + 0.8 in standard form using integers.

Answer 1

Turn -0.5 and 0.8 into a fraction, which would be

\[ y = -\frac{1}{2} + \frac{4}{5}\]

Now find a common denominator for the two fraction and times it on both sides

\[ 10*y = 10 * [-\frac{1}{2} + \frac{4}{5}]\]

Once you do the calculation, put it into standard form. Can you finish it?
