Question

find the equation of the line joining the point (1, 4) and (3, 5) ??????????????
​

Answer 1

Step-by-step explanation:

A(1,4)

B(3,5)

Slope = (y2 - y1) / (x2 -x1)

= ( 5 -4 ) / (3-1)

= 1/2

Now,

Equation of line is :-

y - y1 = m ( x- x1)

=> y - 4 = ( x - 1 ) / 2

=> 2y - 8 = x - 1

=> 2y - x - 9 = 0
