Question

y=3x-2
if y=0
find x
if x=0
find y
graph
|x|0|?|
|y|?|0|

Answer 1

plug in a 0 for y to find the x intercept, then plug 0 in for x to find the y intercept. Those two points then give you enough to graph a line. You only need two points to graph a line.

Answer 2

OK
if x = 0
\[y=3\times( x) -2\]

Just put 0 where x is in th eequaiton.

if y=0
0=3x-2

Start by adding 2 to EACH side of that equation. See if you can take it from there.

Answer 3

If y = 3x-2, plug in 0 for y like this: 0 = 3x-2. Solve for x. Move the -2 over to the other side and divide by 3. Do you know how to do that?

Answer 4

yea thanks guys i will ask for help when i finish with Graphing straight lines

Answer 5

cause my tutor teacher marked it correct but when it come to graphing i got it wrong is this the right answer
|x|0|0.6|
|y|-2|0|

Answer 6

Your coordinates are backwards. When y = 0, x is 2/3. So your coordinate for that point is (2/3, 0). When x = 0, y is -2 so the coordinate for that is (0, -2). That's why your graphing was wrong.
