The sum of two rational numbers will always be <u>rational</u>

, therefore it will always be rational
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

so we're really looking for the equation of a line whose slope is 1/2 and passes through (-4 , 1)
