Question

Find the equation of line joining two points (1, 2) and (2, 3)

Answer 1

y - 2 = 1/1(x-1)

y-2 = x-1

x - y +1 = 0


hope it helped you....

Answer 2

Heya.....

(y - y1) = (y2 - y1) ÷ (x2 - x1) × (x - x1)

Here...(1, 2) and (2, 3)

Therefore...

(Y-2)=3-2÷1-2 ×( x-1)

Y-2=-1(x-1)

Y-2=-x+1

Y=3-x
