Question

What is the equation of the line in standard form that passes through the point (–2, –3) and is parallel to the line y = x + 9?

Answer 1

x – y = 1
x + y = 1
x – y = –5
x + y = 5
i chose the last one

Answer 2

parallel mean that the new line have the same slope of you line: so it will have equation => y=x+q sostitute the x and y of the point, you'll have -3=-2+q => q=-1 so the solution is y=x-1 , the first one!
