13. Write y = 1/2x + 8 in standard form using integers.
To write the equation y = 1/2x + 8 in standard form, we need to get rid of the fraction by multiplying both sides of the equation by 2:
2y = 2(1/2x + 8)
2y = x + 16
Now, let's rearrange the equation so that the variables are on one side and the constants are on the other side:
x - 2y = -16
Thus, the equation y = 1/2x + 8 in standard form using integers is x - 2y = -16.
