Question

What is the equation of a line that goes through the points (1, 4) and (2, 2) ?

Answer 1

Two point form.. You know about it?

Answer 2

See we have a formula for it :
\(y - y_1 = \cfrac{(y_2 - y_1)}{(x_2 -x_1)} \times (x_2 -x_1) \)

where we have two points as \(x_1 , x_2\) and \(y_1 , y_2\)

Answer 3

where we have two points as \(x_1,y_1\) and \(x_2, y_2\) ^ correction.

Answer 4

So just solve for it now. Put \(x_1 = 1\) and \(y_1 = 4\) , \(x_2 = 2\) and \(y_2 = 2\)

in the equation above.

Answer 5

@Annetta_Martin can you do it?
