Write the equation y = -3x + 9 in standard form with integer coefficients.

it is important to know the standard form which is ax + by + c = 0 y = -3x + 9 so then you put ^ this in standard
Ax + By = C is standard form....I thought
oh yeah oopps yep
so first add 3x to both sides of the equal sign and that should get you to your answer
how do I add 3x 2 both sides @texaschic101
y = -3x + 9 ----add 3x to both sides 3x + y = -3x + 3x + 9 -- combine like terms 3x + y = 9 -- see how the -3x and the 3x cancel out on the right side....and this is now in standard form
or if it is easier to understand, write it like this... y = -3x + 9 + 3x + 3x ------------------add 3x + y = 9
just remember, what you do on one side of the equal sign, you have to do on the other side
any questions ?
nice;)
thanks....I try to explain
@texaschic101 I have more ques on my test can u help meh
oh....a test.....um...not supposed to, might get me banned. Not supposed to, if its a test. I wish you wouldn't have said that.
Tell you what....close this question. Then ask me what you need help on. Even though the question is closed, you can still post stuff on it
ok ill do that
ask away
??
Referring to the figure, write the equation of the horizontal line through the point (0,3).
ill use this same graph 4 tha next few ques
Learn this too... HOY -- horizontal line, 0 slope, represented by y = a number VUX -- vertical line, undefined slope, represented by x = a number A horizontal line will always have y = a number. In this case (0,3)...y = 3 and y will always equal 3. And your slope is 0. So your equation is : y = 0x + 3 (because the slope(m) = 0) or it can be written as y = 3
Referring to the same graph, write the equation of the horizontal line through the point (3,0).
Horizontal line through (3,0) slope = 0 y = mx + b 0 = 0(3) + b 0 = b so your equation is : y = 0x + 0 or just y = 0...I think this one confuses me a little.
Referring to the same graph, write the equation of the vertical line through the point (0,3).
VUX -- vertical line, undefined slope, x = a number The vertical line through (0,3)....x = 0 and y = 3 The x will always be 0. so your equation is : x = 0
if you have a vertical line, the the x's will always be the same number if you have a horizontal line, then the y's will always be the same number
and I know this is probably not gonna be used in your future, but you need to learn it to get out of high school
Referring to the same graph, write the equation of the vertical line through the point (3,0).
im sorry my internet was actin up :(
I am not sure about this one simply because it has an undefined slope, but I think it is just gonna be : x = 3 because (3,0)...x is 3
thx 4 tha info @texaschic101 that info bout how 2 find out tha answer really helped thx :)
I try to help when I can. Good luck with the test
i didn't do well :( tha peeps that helped meh b4 didn't help meh out enough i got a freakin D+ man @texaschic101
gtg bye
