Question

Which of the following statements best describes the graph of x + y = 4?

It is a line which intersects the x axis at (4, 4).

It is a line which intersects the y axis at (4, 4).

It is a line joining the points whose x and y coordinates add up to 8.

It is a line joining the points whose x and y coordinates add up to 4.

Answer 1

Why not start by graphing the equation, even tho you weren't asked to graph it? Seeing the graph would tell you a lot. Next, you might want to eliminate the obvously-wrong answers.

Answer 2

ok

Answer 3

i think its D but I'm not sure

Answer 4

is it?

Answer 5

Sorry. I typed info to you but apparently didn't wait to be sure it posted.

Again I would suggest you draw the graph of x+y=4.
To find the y-intercept: Let x=0 and find y.
To find the x-intercept: Let y=0 and find x.

This may be all the info you need to choose the correct answer to this question.

Answer 6

with this I'm pretty sure its C

Answer 7

hyntc: i would much rather help you arrive at the correct answer, and will generally not be telling you that you're "right" or "wrong". Earlier I suggested that you eliminate the worst of the 4 possible answers; have y ou done that?

Answer 8

yes its
(4,4) and if you add it it equals 8

Answer 9

It's great when you explain your reasoning AND end up with the correct answer because you did the problem properly! Congrats. Hope you think, as I do, that we make a good team.
