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?
possible answers: x – y = 1
x + y = 1
x – y = –5
x + y = –5

hartnn · Answer

can u find the slope of given line y=x+9 ?

anonymous · Answer

thats what i cant figure out, cuz i get the rest

hartnn · Answer

the slope of line y=mx+c is m
so what will be the slope of line y=x+9 ?

anonymous · Answer

1?

hartnn · Answer

yes, thats correct.!

hartnn · Answer

now parallel lines have same slope, so the required line also has slope =1
so you can write it as y=x+c
now u have point (-2,-3) on it
just put x=-2 and y= -3 and find c
can u?

anonymous · Answer

yeahh let me give it a try(:

anonymous · Answer

so the right answer would be x-y=1 right?

hartnn · Answer

yes, thats correct!
good work :)
