Question

The equation of the line that goes through the points (−2,6) and (8,5) can be written in general form
(with integer coefficients, positive lead coefficient, and no common factor)

Answer 1

y=-0.1x+5.2

Answer 2

thats what I got but my system keeps telling me that is the wrong answer

Answer 3

it's the right answer though...

Answer 4

General form

Answer 5

Ax + By + C= 0
(with integer coefficients, positive lead coefficient, and no common factor)

Answer 6

they want it in Ax+By+C=0 form...which i thought would be -0.1x+y+5.2=0

Answer 7

but with integer coefficients. multiply both sides by 10

Answer 8

isn't it -5.2 ?

Answer 9

check that, -5.8

Answer 10

now im confused...wouldnt the slope be 10

Answer 11

i meant -1/10...and it says the coefficients have to be positive so thats why im lost

Answer 12

you start with
0.1x+y-5.8= 0 (we can check this is correct 0.1*-2+6 -5.8= 0)
multiply by 10
x+10y-58=0

Answer 13

but 0.1 is negative...how did you get positive

Answer 14

or from slope-intercept form
y= -0.1x +5.8

0.1x + y - 5.8 =0
1x + 10y -58=0
or simply
x +10y -58=0
you can check by plugging in (x,y) values that are on the line

Answer 15

make sense?

Answer 16

yes...thank you
