What's the answer for this ? -5x+11=1/2y
what are you solving for ?
Write in standard form with interger coefficents?
Are you still there?
|dw:1391793995824:dw|
standard form : Ax + By = C -5x + 11 = 1/2y ---- subtract 11 -5x = 1/2y - 11 --- subtract 1/2y -5x - 1/2y = -11 -- standard form has no fractions, multiply by 2 -10x - y = -22 -- multiply by -1 to make x positive 10x + y = 22
Thank You! can i ask something else?
yes
Write the standard form of an equation of the line passing through (-5,1) with slope 3/4?
y = mx + b 1 = 3/4(-5) + b 1 = -15/4 + b 1 + 15/4 = b 4/4 + 15/4 = b 19/4 = b your equation is y = 3/4x + 19/4 but we need Ax + By = C so... y = 3/4x + 19/4 -- subtract 3/4x -3/4x + y = 19/4 -- no fractions, multiply by 4 -3x + 4y = 19 -- multiply by -1 to make x positive 3x - 4y = -19 -- standard form
So wsrite both of them down? or jus the first one?
if you need to show how you got the answer, you might need to write both
if you just need the answer, write 3x - 4y = -19
Ok.. Write the standard form of the equation? a. a horizontal line thorugh (6,-5) b. vertical line thorugh (-2,7)
