Question

Indicate in standard form the equation of the line passing through the given points.

E(-2, 2), F(5, 1)

x + _ y = - _

Answer 1

Find the slope. Use the point-slope form to get the equation of the line. Convert it to standard form.

Answer 2

That doesn't tell me much...

Answer 3

gradient(slope)(m) = (y2-y1)/(x2-x1)
here in your case let's take y2=5,y1=-2,x2=1,x1=2
then,
m = [5-(-2)]/[1-2]
= 7/-1
= -7

Consider a general point P=(x,y) on the line,

Hint : gradient of a straight line is constant.

Now try to work it out..

If no good come here..

Answer 4

Neo, I'm trying to find the equation, not the actual answer itself.

Answer 5

u need da eqn of the st line passing through those given points? isnt it?

Answer 6

OK.. did u try
y-(-2)/x-2 = -7
y+2/x-2 = -7
y+2 = -7x + 14
y = -7x + 12

Answer 7

I updated the question with what I figured out so far.

Answer 8

sephi.. i hav alredy givn u da answer didnt u get it..?

Answer 9

Oh, there we go! Thanks Neo!

Answer 10

It was X + 7y = 12

Answer 11

:-D
