Question

Which equation represents the line passing through the points (3,2) and (-9,6)?
x-3y=9
x+3y=9
3x-y=-9
3x+y=9

Answer 1

first find the slope using the two point
y2-y1/x2-x1


could you do that?

Answer 2

y=4 and x=-12

Answer 3

yeah divide them

Answer 4

that is -0.3 repeating

Answer 5

right?

Answer 6

simple -1/3 is your slope

Answer 7

okay

Answer 8

what's next

Answer 9

wait

Answer 10

Never mind. I got to gp

Answer 11

Thanks anyway

Answer 12

now use
y-y1[=-1/3(x-x1)
where y1=2 and x1= 3

put these value an you willl get x+3y=9
