Question

i have a question. for linear equations AFTER I SOLVE it in like point slope or like y intercept form and ext. how do i put my answer back in general form..

Answer 1

can you give an example of the problem?

Answer 2

idk

Answer 3

You don't know your question?

Answer 4

yes i do can you give me a second

Answer 5

write an equation of the line through (5,5) and parallel to the line 4x+3y+-2

Answer 6

typo in the equation? can you fix it?

Answer 7

yeaj sorry it is and equal =
not +

Answer 8

so what i do is put it in y=mx+b so i can plug it in the calc.
so after in that form what do i do

Answer 9

4x+3y= -2 ?

I would put this in the form y= mx+b so you can find the slope (m)
can you do that ?

the first step is write -4x+ on both sides of the = sign.

Answer 10

no i got the ansewr in y=mx+b but the answer in the box gives it in general form

Answer 11

and i dont have my answer with me so i can tell you

Answer 12

what do you get after you put 4x+3y= -2 in y= mx+b form?

Answer 13

y=-4x-2/3

Answer 14

the whole equation over 3

Answer 15

except y

Answer 16

if you wrote it as y= (-4/3)x-2/3 it would be better.
so the slope is -4/3

if you sub in (5,5) into
y = mx +b with m= -4/3 (parallel to the line they gave you)
5= -4*5/3 +b
to find b
did you find b?

Answer 17

yeah plug in 5 for y and x

Answer 18

so the equation they want (in slope-intercept form) is
y= (-4/3) x +35/3

is that what you got?

Answer 19

yes but they want it in general form i put the answer in intercept form so i can plug it in the calc

Answer 20

standard form is
a x + by = c
where a is positive (and not a fraction)

add +(4/3)x to both sides

then multiply both sides, all terms by 3

Answer 21

ax+by=c or ax+by+c=0

Answer 22

See http://en.wikipedia.org/wiki/Equation_of_a_line#Forms_for_2D_linear_equations
for definitions of the different versions

Answer 23

ax+by+c=0 is general form

Answer 24

y= (-4/3) x +35/3
(4/3)x + y = 35/3
4x+3y= 35
